The amount of energy that an object has can be decreased by decreasing its temperature.
Let us recall that the temperature of a body is a measure of the average kinetic energy of the molecules of the body. The molecules in a body are always in constant random motion.
The kinetic energy possessed by the body is dependent on its temperature. To control the amount of energy that an object has, we either increase or decrease its temperature.
If we want the amount of energy that an object has to decrease, we simply decrease its temperature.

Gymnosperms:-
non-flowering, exposed seeds, pine, or fir fruit.
Angiosperms:-
flowering, seeds enclosed in fruit, garden flowers, and tomatoes
Explanation:
Gymnosperm
Nonflowering and exposed seed
Gymnosperms are the group of plants that do not possess or produce the egg in the enclosed seed which makes there seed naked or exposed
Pine or fir trees
Fir and pine are trees, and more specifically conifers, which belong to the family Pinaceae. of the gymnosperm
Angiosperms
Garden flowers and tomatoes
Tomato plants and garden flowers are the plants that belong to flowering plants or angiosperms.
Seeds enclosed in fruit
In angiosperms, there is a closed ovary that enclosed the egg to protect it. After fertilization ovary turns into a fruit.
Flowering
Angiosperms are the plants that also known as the flowering plant that means these plants are able to produce flowers that are sexual organs of the plant and help in reproduction.
How do plate tectonics support evolution?
When you get cut, your skin cells release hormones that signal platelets to come
and stop the bleeding. Platelets then release more hormones that signal even
more platelets to help stop bleeding. The hormone signals continue until the cut
is closed.
Answer:
This is an example of positive feedback response
Explanation:
Positive Feedback Response in Biology is said to be a phenomenon that occurs when the product or the output of an event or that of a reaction changes the response of an organism to that reaction. Positive feedback response can also happen so as to increase the change or output, then the result of the reaction gets amplified and thus leading to it occuring more rapidly.
An example of positive feedback response is the one from which this question was asked. Another is uterine contractions that takes place childbirth. The hormone oxytocin, created by the endocrine system, goes on to stimulate the contraction of the uterus.
(4pts) Drugs, medicines, and poisons often work by acting on endogenous proteins. They do this by looking similar to a signal molecule and binding to the endogenous protein. Look up these four examples to fill in this chart. Drug, medicine, or poison Looks similar to this endogenous molecule: Binds to this endogenous protein/receptor: Muscarine Acetylcholine muscarinic receptors Prozac Serotonin serotonin transporter protein Ketamine NMDA NMDA receptor Tamoxifen estrogen estrogen receptor
Answer:
Drug, medicine, or poison: Muscarine; Looks similar to this endogenous molecule: Acetylcholine; Binds to this endogenous protein/receptor: muscarinic receptors
Drug, medicine, or poison: Tamoxifen; Looks similar to this endogenous molecule: estrogen; Binds to this endogenous protein/receptor: estrogen receptor
Drug, medicine, or poison: Prozac; Looks similar to this endogenous molecule: Serotonin; Binds to this endogenous protein/receptor: serotonin transporter protein
Drug, medicine, or poison: Ketamine; Looks similar to this endogenous molecule: NMDA; Binds to this endogenous protein/receptor: NMDA receptor
Explanation:
Muscarine is a poisonous natural product found in certain mushrooms. It is similar to acetylcholine and competes with acetylcholine at its receptor binding sites.Signs of muscarine poisoning include salivation, lacrimation, vomiting, diarrhea, abdominal pain, bradycardia, etc.
Tamoxifen is a selective estrogen receptor modulator. It is similar to estrogen and acts by inhibiting the effects of estrogen in the breast tissue. It is used to prevent and treat breast cancer in men and women.
Prozac is an antidepressant which belongs to th class known as selective serotonin reuptake inhibitors. It looks similar to serotonin and inhibits its action by competing with serotonin for its binding site. It is used for the treatment of depression disorders.
Ketamine is an NMDA (N-Methyl-D-aspartate) receptor antagonist. NMDA receptor antagonists are a class of drugs that work by inhibiting the action of the NMDA receptor. They are commonly used as anesthetics for animals and humans to induce a state of anesthesia known as dissociative anesthesia.

air currents, or
Answer:
This shows the interaction between the earth and sun.
Explanation:
There is a variation in the amount of heat that reaches the different latitudes as the interaction between the sun and earth which firms different angles of incidence on the surface. The rays of the sun are more concentrated in mid latitudes that is the tropics and are slanting towards the poles this due the tilt in axis of earth. This variation lads the warm air to rise and reach the poles and similar the cold polar air reaches the tropics and develops a cycle of convective cells. This leads to a latitudinal balance in temperatures.Which statement did Virchow's work add to the cell theory?

becuse When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault.
The average animal cell generally spends about 24 hours completing a cell cycle (18-20 hours of that being in interphase). The fastest dividing animal cell completes a cell cycle in about 9-10 hours. What would be some reasons for more rapid cell division
Answer:
The lack of Mad1 protein can cause faster cell division.
Explanation:
The Mad1 protein is responsible for regulating the fixation of chromosomes in spindle microtubules, during cell division. With the presence of this protein, anaphase is prevented from starting while the spindle, where the chromosomes attach, is formed.
Without this protein, this check is not done and cell division occurs faster, which is one of the reasons why cell division can be accelerated.
The cell cycle is the division of cells and the replication of the genetic material. The cell cycle requires 24 hours to complete the cell cycle, whereas some animals complete the cell cycle in 9-10 hours due to a lack of Mad1 proteins.
The correct answer is:
Lack of Mad1 proteins.
The function of Mad1 proteins are:
Mad 1 proteins regulate the attachment of chromosomes to the spindle microtubules. The proteins halt the cell cycle in the anaphase until the spindle apparatus is formed.The lack of protein in the other organisms causes rapid cell division. The protein is a checkpoint and arrests the cell cycle in anaphase, however, the lack of these proteins will cause a faster cell cycle.
Therefore, lack of Mad1 proteins will result in a faster division, because no checkpoint will be available in the anaphase of the cell cycle.

Why is the Pericycle absent in the roots and stems of some hydrophytes?
Answer:Essay on Hydrophyte | Plants
Article Shared by
The below mentioned article provides an essay on hydrophyte.
Hydrophyte embraces all the different and varying plant forms that adapted to live under direct influence of free water or in waterlogged soil, e.g. a small number of ferns and angiosperm. Gymnosperms have not migrated into aquatic habitats.
Hydrophytes, also called hydrophytic plants, are classified according to forms:
Submergent, Floating and Emergent. Submergent hydrophytes grow and remain entirely submerged below the surface of water throughout life. Floating hydrophytes have leaves or shoots that float on top of water surface. Emergent hydrophytes have roots anchored to hydric soil, but a portion of shoot lies above water surface.
The different form of hydrophyte exhibits the following characteristics that help them to survive in water and waterlogged soil:
i. Increase in leaf surface that helps plants for floatation.
ii. The presence of air chambers that assist in buoyancy of the plant.
iii. Stomata, if present, nonfunctional because the plants need not regulate transpiration due to abundance of water in their environment.
iv. Reduction of xylem because the hydrophytes need not conserve water.
v. Reduction in mechanical and protective tissue as water pressure supports them.
vi. Hydrophytes have thin cuticle or lack it. Because the functions of cuticle like protection from strong sunlight, conservation of water and deterrence of insects are not required by hydrophytes. They are protected from excess sunlight by surrounding water; no question arises for water conservation as they have abundant free water in their environment; the hydrophytic angiosperms suffer little predation by aquatic animals.
Due to the thinness of cuticle the leaves absorb nutrients from the water directly. But the major bulk of minerals are absorbed by roots and transported to the leaves. As there is no transpiration pull like land plants the transportation of minerals occur through root pressure. Hydathodes are very common in the leaf tips of many submerged hydrophytes. Transportation of water occurs as a bleeding stream ending in hydathodes. The opening of hydathodes may be large.
vii. Stomata when present may be many in number and occur on upper surface of floating leaves (epistomatous).
viii. Roots are small and reduced in all respects as water can diffuse directly into leaves.
ix. Formation of special roots and these are negatively geotropic and designed to function in gas exchange. Such roots are termed as pneumatophore and present in halophytes.
x. Hydric soils have diluted oxygen and minerals and the hydrophytes adapted to absorb nutrients directly from water.
xi. The piliferous layer scarcely has (or no) root hairs. Root hairs are entirely absent from Ceratophyllum.
xii. The piliferous layer is not cutinized/suberized and so absorptive in function. Moreover the turgid piliferous zone provides mechanical strength, as mechanical cells are absent in hydrophytic roots.
xiii. The cortex of root is wide and provided with air cavities.
xiv. Xylem of root and stem is poorly developed and has thin walls. Vessels are absent in many hydrophytes. In the root of Potamogeton (Fig. 29.9A) the vascular tract in the centre is occupied by a large xylem cavity. The reduction in xylem is due to the fact that in hydrophytes no elaborate system of water absorption is required as all the epidermises of plant body are capable of water and mineral absorption.
xv. The stem of submerged hydrophytes is very weak and flexible. It moves according to the direction of flow of water currents.
xvi. The epidermis in the stem of submerged hydrophytes is uniseriate. It is not cuticularized and in some cases the cells have cellulose walls only. As a result the epidermal cells can absorb mineral salts and gases dissolved in water directly.
xvii. The cortex is wide and has large air chambers. The air chambers may be arranged symmetrically e.g. Myriophyllum (Fig. 29.9B) or scattered irregularly all over the cortex, e.g. Elodea, Hydrilla, Hippuris etc.
xviii. The cells of cortex have low osmotic pressure. The cells contain chloroplastids that help in photosynthesis.
xix. The vascular tissues in stem of submerged hydrophytes are not well developed. Endodermis and pericycle are indistinct. The vascular tissues are mostly composed of phloem.
Hydrophyte
xx. Though the endodermis is not distinct many hydrophytic angiosperms have the innermost layer of cortex that functions as endodermis. This endodermoid layer is present in submerged roots, stems and leaves. It is assumed that this layer is involved in channelizing the flow of water through reduced xylem.
Explanation:
Hydrophytes are aquatic plants that are especially suited for living in aquatic environments.
What are hydrophytes?In order to survive, a hydrophyte, also known as an aquatic macrophyte, must either be completely submerged in water, or in some cases be allowed to float on the surface of the water.
Aquatic plants can usually be categorized into 4 main type: floating plants, deep water plants, marginal plants and oxygenating plants. For a more in-depth description of the various types, please see our page on plants for ponds.
The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants.
Therefore, Hydrophytes are aquatic plants that are especially suited for living in aquatic environments.
