The invention of the microscope led to the discovery of the cell by Robert Hooke. While looking at cork, Hooke observed the box-shaped
xstructures, which he called "cells" because they reminded him of the cells (rooms) found in monasteries. This discovery led to the
development of the cell theory. Credit for developing the cell theory is usually given to two scientists: Theodor Schwann and Matthias
Schleiden. The cell theory was then proposed by Theodor Schwann in 1839. There are three parts to this theory.

How do cells get made?

The cell cycle is the process through which new cells are generated from pre-existing cells. One cell is capable of self-replication, giving rise to two additional daughter cells. Every cell cycle requires the completion of two main tasks. Cells must first duplicate their DNA exactly.

What makes it called a cell?

After examining a piece of cork under a very early microscope, Robert Hooke proposed the name "cell" in 1665, derived from the Latin cella, which means "storeroom or chamber." Furthermore, it is reported that he compared the rectangular spaces to some monastic cells.

Which are ways that humans can lower biodiversity as they us environment? Check all that apply. A. Converting a forest to soccer fields B. Spraying pesticides on lawns An C. Building roads across tundra D. Replacing riverbanks with concrete bulkheads and​

Answers

Answer:

A, B, C, and D

Explanation:

All of the options represent ways by which humans can lower biodiversity as they use the environment.

By definition, biodiversity or biological diversity of an area refers to the total number of living organisms that are domicile in that area.

Converting a forest to a soccer field requires that the variety of plants and animals in the forest are removed and the forest soil is planted with turfs in their place. Thus the biodiversity of the forest has been greatly reduced in other to pave way for a soccer field.

A pesticide is an agrochemical that kills pests. Pests are biological organisms even if they are not that desirable on the lawn. Thus, killing them off using a pesticide is a way of reducing the biodiversity associated with the lawn.

A tundra represents an ecoregion with its own characteristic plants and animal, even if they are few. Hence, building roads across tundra requires that portions of the biodiversity are removed to pave way for the road.

Riverbanks serve as habitats for a variety of living organisms. Replacing them with concrete bulkheads means that the habitat is lost and the organisms displaced. Thus, the biodiversity of the region gets reduced.

Therefore, options A, B, C, and D are all correct.

8. a) How are the events in the menstrual cycle triggered by the body? (1 point)


Will be marking brainliest!!

Answers

There is a supply of undeveloped eggs in the ovaries. At the beginning of the menstrual cycle, between 6 and 12 undeveloped eggs in the ovaries start to mature. A layer of cells grows around them. At around day 5 of the menstrual cycle, the biggest follicle will continue to grow for another week. At around day 14, the follicle breaks apart, and the wall of the ovary ruptures. The egg is released from the ovary into the fallopian tube, where it can get fertilized. This process is called ovulation. The uterus also changes during the course of the menstrual cycle. It has a lining of cells on the inside, kind of like a cushion with a lot of blood vessels. Fallopian tubes connect the ovaries and the uterus. The uterine cycle begins with menstruation. This is the process through which most of the lining and blood from the last uterine cycle are cleared out of the uterus to prepare for a new attempt at pregnancy. Starting at around day 5, the lining starts to grow. It builds back up to prepare a place for the egg to grow if it gets fertilized. After ovulation, the egg reaches the oviduct. If sperm cells have entered the vagina during intercourse, fertilization may occur at any time in the next two weeks. Then the fertilized egg will move into the uterus and implant itself into the lining, where development will begin.

Please mark BRAINLIEST!

The events in the menstrual cycle are primarily triggered by hormonal signals from the body. The menstrual cycle is a complex process regulated by the interplay of hormones produced by the hypothalamus, pituitary gland, and ovaries.

1. Hypothalamus: The hypothalamus, a region of the brain, releases gonadotropin-releasing hormone (GnRH) in a pulsatile manner. GnRH stimulates the pituitary gland.

2. Pituitary gland: In response to GnRH, the pituitary gland secretes two important hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH).

3. Follicular phase: At the beginning of the menstrual cycle, FSH stimulates the growth and maturation of ovarian follicles, which contain the developing eggs (oocytes).

As the follicles grow, they produce estrogen, a hormone that helps prepare the uterus for a possible pregnancy.

4. Ovulation: As the estrogen levels rise, it triggers a surge in LH production by the pituitary gland. The LH surge leads to the release of a mature egg from the ovary, a process called ovulation.

5. Luteal phase: After ovulation, the ruptured follicle in the ovary transforms into a structure called the corpus luteum. The corpus luteum produces progesterone, which prepares the uterus for potential implantation of a fertilized egg.

6. Menstruation: If pregnancy does not occur, the levels of estrogen and progesterone decline. This drop in hormone levels triggers the shedding of the uterine lining, resulting in menstrual bleeding.

Describe how knowing the column (group) number is a "cheat code" for determining the number and types of bonds that an element can form.

Answers

Answer and Explanation:

The columns of the periodic table are able to inform the number and type of connection that the elements can make. This is because the number of each column informs the number of electrons in the valence layer of the elements. The amount of electrons in the valence layer is what determines the amount and type of bond that the elements make. The elements in column 1, for example, have 1 electron in the valence layer and therefore will make 1 covalent bond. The elements of columns 15, as another example, have 5 electrons in the valence layer and will need to make 3 ionic or covalent bonds.

To describe how knowing the group number is a cheat code to determine the type of bonds that can be formed, we should first define periodic table

What is periodic table

Periodic Table is a series of elements in which they are arranged in increasing order of their atomic number from left to right but the table also have groups (column) from up to downwards each group have atoms with same number of electrons in their last shell due to which they all have almost similar properties such as same magnetic properties ,same number of bonds formation, metallic character .

We can say that similarity in properties of members of same group is due to same number of valance electrons . For example group 14 i.e. Carbon Family ,all elements of this group will have 4 valance electrons and will form 4 bonds by sharing of their electrons.

Explanation:

As temperature increases, absolute brightness increases

As temperature increases, absolute brightness increases. Therefore, option (C) is correct.

What is absolute brightness?

Absolute brightness, also known as absolute magnitude, is a measure of the intrinsic luminosity of a star, which is its total energy output per unit of time. Absolute brightness is defined as the brightness a star would have if it were placed at a standard distance of 10 parsecs (32.6 light years) from Earth. This standard distance allows astronomers to compare the luminosity of stars with different distances from Earth.

Absolute brightness is an important measure for astronomers because it helps them determine the true luminosity and size of a star. It also helps astronomers classify stars based on their luminosity and temperature, which is related to their evolutionary stage. For example, main sequence stars, which are stars in the process of burning hydrogen to helium, are classified based on their temperature and absolute brightness

Answers

Answer:

1) NADP is the reducing agent produced by the light reactions of photosynthesis and is consumed in the Calvin cycle of photosynthesis and used in many other anabolic reactions in both plants and animals.

3) Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. Physically, photosystems are found in the thylakoid membranes. There are two kinds of photosystems: photosystem I (PSI) and photosystem II 

● PhotosystemSII acts first during the light transformation process in photosynthesis.

● Photosystem1 is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from 

plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by carrier NADPH.

Compare the effect of acetylcholine on cardiac muscle with its effect on skeletal muscle. Can you explain the mechanistic basis for the difference

Answers

Answer:

The action of the neurotransmitter acetylcholine, released by the vagus nerve in the heart, slows the heart rate and weakens the force of contraction. The skeletal muscle has the ability to perceive a stimulus and respond to it. As regards skeletal muscles, the stimulus is chemical in nature: acetylcholine released by the motor nerve ending. The response of the muscle fiber is the production and propagation along its membrane of an electrical current (action potential) that causes muscle contraction.

Explanation:

Acetylcholine is one of the most abundant neurotransmitters in the central and peripheral nervous system. Acetylcholine receptors are nicotinic (ionotropic) and muscarinic (metabotropic GPCR). In skeletal muscle of adults, acetylcholine binds to the alpha subunit of the nicotinic channel, which are two of the five subunits that make up the pore of this channel. Acetylcholine released by the nerve ending binds to the receptor in the sarcolemma and triggers an electrical current - the action potential. This spreads along the sarcolemma and causes a signal to pass from the T tubule to the sarcoplasmic reticulum in the triad, which then releases calcium ions (Ca ++). Once the calcium ions are released, by diffusing between the actin and myosin protein filaments, they cause the myofibrils to contract. On the other hand, in cardiac and smooth muscle cells, acetylcholine binds to 7M proteins, which do not function as channels, but are typical members of the GPCR class A superfamily. One of the physiological mechanisms of acetylcholine is the regulation of the heart rate, through the mobilization limited to the inner face of the plasma membrane of the dimer bg of protein G. This dimer transduces the specific binding of the ligand with its receptor in the plane of the membrane, thanks to its proximity with the ion channel or with enzymes bound to the plasma membrane. This can be done because its g subunit remains attached to the inner face of the membrane.

It helps in determining the occurrence and existence of particular kind of species on planet earth. It can also be used to trace the development and passage of a particular kind of trait from one generation to the another. It can also be used to trace back various geological events that occurred on planet earth like volcanic eruption, plate tectonics, and others. The geologists used it for tracing the geological activities that occurred in the history of earth. Archaeologist study about rocks and fossils to trace back the geological time scale. Paleontologist study the existence of a particular species via studying the fossil evidences and reconstructing the primitive conditions by developing a geological time scale. They trace the evolutionary history of organisms.
