By studying the distribution of different types of fossils, geologists have determined that some tectonic plates have traveled great distances.
Evidence to support this is that -
A. fossils of organisms that lived in warm climates have been found in arctic environments.
B. species of organisms in the fossil record have changed over geologic time.
C. some fossilized organisms have only been found on only one continent.
D. the oldest known fossils, found in the deepest rock layers, represent ocean organisms.

Answers

Answer:

the answer is A

Explanation:

The evidence to support the idea that some tectonic plates have traveled great distances is option A, "fossils of organisms that lived in warm climates have been found in arctic environments."

What does the distribution of fossil fuels tells us?

The distribution of fossils can provide important clues about how continents and tectonic plates have moved over time. When continents or plates separate, they can carry with them the fossils of organisms that were living in that area at the time. As a result, the same types of fossils can be found in geographically distant locations that were once connected.

For example, the discovery of fossils of tropical plants and animals in polar regions provides strong evidence that those regions were once located closer to the equator and have since moved to their current location. This phenomenon is known as "paleogeography" and has been instrumental in understanding the movement of tectonic plates and the history of the Earth's continents.

Both mitosis and meiosis begin with a diploid cell that contains replicated chromosomes. What are the main differences between these two processes, and what types of daughter cells produced by each? Meiosis has four cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has two cell divisions and results in two identical daughter cells. Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells. Mitosis occurs in gametes to increase genetic variation in daughter cells, while meiosis occurs in body cells for growth and repair. Mitosis produces genetic variation in daughter cells and increases the number of chromosomes, while meiosis occurs in body cells for growth and repair.

Answers

Answer:

Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.

The main differences would be that Meiosis has 4 cell divisions and Mitosis had 2 cell divisions. Meiosis results in 4 haploid daughter cells and Mitosis results in 2 identical daughter cells.

Another big difference between the two could be that Meiosis produces genetic variation in the daughter cells and increases the number of chromosomes whilst Meiosis occurs in body cells for growth and repair. Each process has a different job.

Alexis is using models of the cell membrane to compare the types of cellular transport. One

model shows a molecule entering through a protein pump. Which ope of cell transport is
being modeled?
A
diffusion because protein pumps are needed to move substances from a higher
concentration to a lower concentration
8
endocytosis, because protein pumps transport substances that are too large to
pass through the cell membrane
active transport, because protein pumps are needed to move substances against a
concentration difference
D
osmosis, because protein pumps allow water to cross the cell membrane

Answers

Answer:

C. active transport, because protein pumps are needed to move substances against a concentration difference

Explanation:

There are two major types of transport in living cells namely: passive transport and active transport. The passive transport moves molecules down a concentration gradient and hence, do not need energy (ATP) to occur. However, on the other hand, ACTIVE TRANSPORT moves substances against their concentration gradient, thus, require energy input.

Active transport makes use of PROTEIN PUMPS to achieve this process. Hence, in this case where Alexis is using models of the cell membrane to compare the types of cellular transport. The model that shows a molecule entering through a protein pump is modelling ACTIVE TRANSPORT.

Explain two ways materials can enter the cell through passive transport. Include in your answer: the types of substance that is transported, the concentration gradient, and any structures in the cell membrane required to be used.

Answers

Answer:

There are two types of passive transport, you have diffusion and facilitated diffusion. Another one could be osmosis which is diffusion of water molecules.

Explanation:

Diffusion is solute passing through the membrane from a higher concentration to a lower concentration until it reaches equalibrium. Osmosis is the same as diffusion only it passes water molecules and it uses aquaporins  which is a structure in the membrane to help the water pass. Finally you have facilitated diffusion that uses protiens for diffusions but still not using energy and that is why it is passive transport. The type of substance that can be transported are molecules with no charge or non-polar molecules. Lmk if this helps. Sorry in advance if the answer is not clear to understand.

what is cellular respiration?

The process in which conversion sugars into energy (ATP) occur by cells called as cellular respiration. It can be used by a number of cellular components as a source of energy.

There are two types of respiration occur such as aerobic and anaerobic respiration.

Aerobic respiration occur in presence of oxygen which act as a powerful electron acceptor, mostly seen in eukaryotes.

In case of prokaryotic organisms such as bacteria and archaebacteria, other types of respiration occur.

Carbon dioxide is also a product of cellular respiration which is released as a waste product.

There are three major types of cellular respiration occur such as aerobic, lactic acid fermentation, alcoholic fermentation.

In aerobic respiration 36 ATP, where as in lactic acid fermentation 2 ATP and alcoholic fermentation 2 ATP are produced.

Explanation:

Suppose insects that feed on the plants were placed inside the growth chamber as well. Predict how this might affect the levels of CO2 in the growth chamber. How does this model, on a smaller scale, represent the cycling of carbon through Earth's systems?

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the diagram illustrating the growth chamber. However, since insects also produce/exhale carbon dioxide (CO₂) as a waste product, the level of CO₂ in the growth chamber will increase since insects will serve as an additional source for the production of CO₂.

This model shows how carbon is been cycled though the earth's systems. The CO₂ released/exhaled by animals is been inhaled by plants and used for the production of food substance like glucose (through the process of photosynthesis). Animals eat these plants and then release carbon from these food sources as CO₂ which is taken up from the environment again by plants.

Answer:

- Controls the entry of chyme into the duodenum: A. Pylorus

- Controls the entry of chyme into the colon: H. Ileocecal valve

- Substance that helps make or break a chemical bond: I. Enzyme

- A component of gastric juice: G. Hydrochloric acid

- Organ that releases bile into the small intestine: E. Gallbladder

-  Organ that synthesizes bile: J. Liver

- Fingerlike projection of small intestinal lining: D. Villus

- Absorption mechanism that requires energy: B. Active transport

- Absorption mechanism that does not require energy: C. Diffusion  

- Carries fat-soluble vitamins: F. Lymphatic system

Explanation:

The pylorus is a part of the digestive system that connects the stomach to the duodenum. The ileocecal valve is a muscle localized between the ileum of the small intestine and the colon, whose main function is to limit the reflux of colonic contents. Gastric juice is a liquid consisting of hydrochloric acid, lipase, and pepsin, whose main function is to inactivate microorganisms. The gallbladder is a small organ that in combination with the small intestine are reservoirs for bile acid and regulate the biliary secretion of this acid. The bile acid is a fluid secreted by the liver that helps to digest lipids in the small intestine. Intestinal villi (villus in singular) are finger-like projections that increase the surface area for the absorption of nutrients in the small intestine. Active transport is the movement of molecules across cell membranes by using energy from ATP hydrolysis or by using an electrochemical gradient. Diffusion is the movement of molecules across cell membranes from a side of the membrane with higher concentration to the other side with lower concentration. An enzyme is a molecule (generally a protein) that is capable of accelerating the rate of a chemical reaction. Fat-soluble vitamins are absorbed in the small intestine and then they are transported through the lymphatic system to be released into the bloodstream.

Lilah has gained a lot of weight recently, she works out and watches her food intake, but she is still gaining weight. When she visited the doctor, he told her she had a problem with one of her endocrine glands. Which gland would most likely have an issue with maintaining the breakdown of food?

Answers

The pancreatic exocrine gland, is not found directly in your brain or neck region where most body glands are, instead it’s found in your pancreas. Now pancreatitis, pancreatic cancer, of Type 1-2 Diabetes can all be a cause of the decreased function of the pancreas, but I would suggest Lilah get checks by her Physicians and hopefully he can see exactly what is causing the problem, if it’s pancreatitis, the doctor can put her on pain medications and changed up her diet, or if it’s a severe case she might need surgery.
