Answer:

A) Chloroplasts transform light energy into chemical energy.

Explanation:

Chloroplasts are plastids, cellular organelles inherent in plant cells, which contain a green pigment, chlorophyll, by which they perform photosynthesis.

Photosynthesis is a process in which, with the help of chlorophyll, solar energy is converted into chemical energy in order to use that chemical energy (ATP) for the synthesis of organic matter from inorganic matter (CO2 and H2O).

Answer:

C. Chloroplasts transform light energy into chemical energy.

Answer:

water to move into the cell.

Explanation:

Osmosis is the process by which water moves from a region of low solute concentration (high water conc.) to a region of high solute concentration (low water conc.) across a semipermeable membrane. The movement of water is initiated by the formation of an osmotic gradient i.e. difference in concentration between the two sides of the membrane.

In this case, an animal cell is said to be surrounded by fresh water. This means that the solution in the animal cell is HYPERTONIC (high in solute concentration) to the solution in the extracellular environment, which is HYPOTONIC. This osmotic pressure causes water to move into the animal cell i.e. from the region of high water conc. (freshwater) into region of low water conc. (animal cell), causing the cell to burst.

Answer:

The nitrogenous bases form hydrogen bonds between opposing DNA strands to form the rungs of the "twisted ladder" or double helix of DNA or a biological catalyst that is found in the nucleotides. Adenine is always paired with thymine, and guanine is always paired with cytosine. These are known as base pairs.

C. Amplifying a stimulus to move toward an endpoint

Explanation:

The mechanism of inputs and outputs are operated by biological systems. It is either it is caused by an event or it is causing a certain event. Feedback is very important in this system. Feedback loops are the paths in which a change to the system brings about an alarm that actually brings a certain result. In a positive feedback loop, the product of a reaction brings an increase in the reaction. This is carried out by amplifying effects of a product (stimulus) to move toward an endpoint.

Option C is the correct answer.

Answer: below new fossils

Explanation:

Rocks are usually arranged in Layers of which the oldest  are found in the bottom and the recent rock layers found on the top. This is in line with the  Law of superposition which states that every rock layer is older than the one which lies above it, This law together with the Law of faunal / fossil succession helps us to understand the assemblage of fossils and how they succeed each other with time.  From this, we can say that older fossils in a rock will lie farther below a rock layer leading to the oldest fossils occurring at the deepest part of the rock layers and the newest fossils appearing  at the top of rock Layers.

We can therefore say that Older fossils appear in rock layers–below new  fossils.

Answer:below new fossils

Answer:

The correct answer is ''The scientific study of heredity''

Explanation:

Genetics is a branch of biology that studies how hereditary characters are transmitted from generation to generation and the diversity that exists among living beings. Inheritance is the physical and biological characteristics that we share with our family and that can determine our appearance and our biological characteristics, that is, our phenotype (eye color, skin type, etc.) as well as our internal characteristics. All of this is largely derived from our genetic components, that is, our genotype.

Answer:

where species lives like water are the natural habitat of fish

Answer:

the correct answer is: "c. 23, 46"

Answer:

The sum of an organism's observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism's parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype

Answer:

The likely explanation is that population 1 had traits which were more favorable to its survival than population 2's in the new conditions.  It wouldn't have to do with food competition, but the traits they already have that may or may not be conducive to their survival in the new conditions.

Explanation:

Let me explain. Say a drought occurred on an island. Population 2 relied on eating bugs that lived in the green grasses. Population 1 relied on eating cactus fruit, which is drought-resistant. Say that because of the drought, population 2 started to decrease since there were less bugs to eat because the grasses dried up. Population 1 is unaffected because the bugs they eat were still in abundance.

This all has to do with the concept of natural selection. Species with traits that are good for their environment will likely do well unless a change in conditions occurs which makes their traits no longer favorable.

Hope that makes sense!

Answer:

Salinity affects production in crops, pastures and trees by interfering with nitrogen uptake, reducing growth and stopping plant reproduction. Some ions (particularly chloride) are toxic to plants and as the concentration of these ions increases, the plant is poisoned and dies.

Answer:

Question 26.

B. deposition

Question 21.

Erosion is a destructive force because they disassemble landforms and ultimately destroy the features. Kind of like cultural traits/aspects being diminished. Whereas, deposition is a constructive force because the depositing of sediments can literally form entire landforms- like sand dunes. It takes bits by bits or sediment by sediment to build an entire structure.

Explanation:

Answer:

The correct answer is NMDA receptor acts as a molecular coincidence detector.

Explanation:

The hippocampus works entirely for memory processes (especially new learning). Lasting depression (LTD) is also considered as another form of expression of synaptic plasticity. Long-term potential occurs when pyramidal neurons are depolarized and stimulated by excitatory input. The neurophysiological basis for LTP is certainly related to a subtype of NMDA of the glutamate receptor. This receptor behaves as a coincidence detector between pre- and post-synaptic activity, with an increase in glutamate release at the presynaptic level coinciding with a Postsynaptic depolarization that allows the entry of ca2 +. The NMDA receptor has been proposed as the basic mechanism of learning, because it has the ability to associate different signals, for all this it is necessary to know what neurotransmitters are, their function and what is the role of the receivers in them.

The modern synthetic theory of evolution explains evolution in terms of genetic variation in a population that leads to the formation of a new species and explains the contribution of factors such as genetic variation, reproduction and geographic isolation, and natural selection.

The "modern synthesis" describes the early- to mid-century formulation of evolutionary theory, which reconciled classical Darwinian selection theory with a new population-oriented approach to Mendelian genetics, which attempted to explain the origins of biological diversity.

The factors which is involved in Modern synthetic theory can be broadly divided into three main concepts:

1. Genetic variation

2. Natural selection

3. Isolation

The modern synthesis of the theory which differs from Darwinian evolution in that it expands on the theory to include genes as the medium by which traits are passed down.

Thus, the modern synthetic theory of evolution explains evolution in terms of genetic variation in a population that leads to the formation of a new species and explains the contribution of factors such as genetic variation, reproduction and geographic isolation, and natural selection.

Answer:

diabeytes insupidus

Explanation:

Another name for antidiuretic hormone (ADH) is arginine vasopressin.

It is made by the hypothalamus in the brain.

It is stored in the posterior pituitary gland.

This hormone helps in regulation of the amount of water in blood.

When damage occurs to the antidiuretic hormone (ADH)-producing cells in the hypothalamus from head trauma, intracranial tumors, or neurosurgery, what disorder is suggested by a large diuresis of very dilute urine diabeytes insupidus.

Answer:

The correct order would be - bare rock - lichen - mosses - grass and wild flowers - shrub and trees - insects small birds and trees.

Explanation:

Primary succession is process of new land creating or bare rock exposure to habiated by the any species for the first time on the particlular land. There are different stages or order of the suucssion that take pace in a particular order that ivolves bare rocks whic is exposed to various abiotic condition that leads to next stage of poineers like lichen and thand moses.

Next stage includes the species of annual herbaceous plants and than perrinnial herbaceous plants and grasses. Shrubs and trees comes in the next stagewith birds and the insects and than large shady trres.

Thus, the correct order would be - bare rock - lichen - mosses - grass and wild flowers - shrub and trees - insects small birds and trees.

Answer:

Rh-negative

Explanation:

Erythroblastosis fetalis is a clinical condition whereby maternal antibodies begin to attack the fetal red blood cells due to incompatibility in the Rh of mother and fetus. Rh, which stands for Rhesus factor, can either be positive (Rh+) or negative (Rh-).

However, this condition (erythroblastosis fetalis) occurs in mothers/women who are Rh-negative. When an Rh- mother carries a fetus that is Rh+, the antibodies in the white blood cells of the mother identifies the blood cells of the fetus as FOREIGN, hence, begin to attack it.

However, one preventive measure is that pregnant women who are Rh-NEGATIVE must be treated with injections called Rh immunoglobulin to prevent their antibodies from attacking their baby's red blood cells.
