Why do land plants need to conserve water

Answers

Answer: Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water loss.

What is brain?

The part the nervous system that contains the cerebrum and cerebellum is the brain. The brain is an organ in the body that controls different other activities in the body. Almost everything in the body is controlled by the brain. The three main parts of the brain is; cerebrum, cerebellum, brainstem. The cerebrum controls speech and emotion, the cerebellum controls movement and the brainstem controls sneezing, coughing.

Spinal cord is a part of the nervous system transports information between the brain and other parts of the body. The spinal cord is a tubular and thin structure composed of nervous tissue. The spinal cord functions are to the transmission of neural signals among the brain and other parts of the body. Spinal Cord is necessary because the brain communicates with the body through it.

Thus, the brain sends information by the spinal cord to the peripheral nerves everywhere to the body that serves to regulate the muscles and inner organs.

1. Describe one observation that supports the theory that mitochondria and chloroplasts originated as independent prokaryotic organisms


2.Explain how a symbiotic relationship like the one described in the endosymbiotic theory would have benefited each cell.

Answers

Answer: hope the below answers will help

Explanation:

1 and 2 in this paragraph

SKILLS TO DEVELOP

Briefly describe what is meant by the endosymbiotic theory.

Give some evidence supporting the theory that mitochondria and chloroplasts may have arisen from prokaryotic organisms.

It is thought that life arose on earth around four billion years ago. The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. In this theory, the first eukaryotic cell was probably an amoeba-like cell that got nutrients by phagocytosis and contained a nucleus that formed when a piece of the cytoplasmic membrane pinched off around the chromosomes. Some of these amoeba-like organisms ingested prokaryotic cells that then survived within the organism and developed a symbiotic relationship. Mitochondria formed when bacteria capable of aerobic respiration were ingested; chloroplasts formed when photosynthetic bacteria were ingested. They eventually lost their cell wall and much of their DNA because they were not of benefit within the host cell. Mitochondria and chloroplasts cannot grow outside their host cell.

Evidence for this is based on the following:

Chloroplasts are the same size as prokaryotic cells, divide by binary fission, and, like bacteria, have Fts proteins at their division plane. The mitochondria are the same size as prokaryotic cells, divide by binary fission, and the mitochondria of some protists have Fts homologs at their division plane.

Mitochondria and chloroplasts have their own DNA that is circular, not linear.

Mitochondria and chloroplasts have their own ribosomes that have 30S and 50S subunits, not 40S and 60S.

Several more primitive eukaryotic microbes, such as Giardia and Trichomonas have a nuclear membrane but no mitochondria.

Although evidence is less convincing, it is also possible that flagella and cilia may have come from spirochetes.

EXAMPLE 7.8.1

Briefly describe what is meant by the endosymbiotic theory.

Give three points of evidence supporting the theory that mitochondria and chloroplasts may have arisen from prokaryotic organisms.

Solutions

The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes.

Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission.

Mitochondria and chloroplasts have their own DNA which is circular, not linear.

Mitochondria and chloroplasts have their own ribosomes which have 30S and 50S subunits, not 40S and 60S.

Summary

The endosymbiotic theory states that mitochondria and chlopoplasts in today's eukaryotic cells were once separate prokaryotic microbes.

Answers

Answer:

The offspring will be black because they are heterozygous for a dominant trait that is controlled by monogenic inheritance.

Explanation:

Guinea pigs will be heterozygous because they inherit a dominant allele that encodes for the black color and a recessive allele associated with the white color. Heterozygosity is a genetic condition associated with the presence of two alleles at a locus which are inherited from both parents, one from the mother and the other from the father

B-are made out of organic material that stores the sun energy

C-form where there are frequent earthquakes and volcanic activity

D- are produced high in the mountains where temperatures are low

Answers

Answer:

maybe C i'm so sorry if this is wrong

Explanation:

Organic materials and silt build on top to produce fossil fuels. Heat and pressure transform organic materials into coal, petroleum, or natural gas. Therefore, option (A) is correct.

What are fossil fuels?

An extracted and burnt fossil fuel is a hydrocarbon-containing substance that naturally originated in the Earth's crust from the remnants of extinct plants and animals. Coal, oil, and natural gas are the three primary fossil fuels.

Because certain sedimentary rocks contain trapped fossil fuels, sedimentary rocks and fossil fuels are connected. As organic materials and silt build up on top over time, fossil fuels are created. The organic material undergoes a chemical shift under heat and pressure, turning it into coal, oil, or natural gas.

How do the respiratory and circulatory systems work together to make gas exchange possible?Giving brainliest to first right answer

Answers

Answer:

Answer: The respiratory system moves air in and out of the body. When you breath in oxygen this creates oxygenated blood. The blood moves through the aorta which then distributes the oxygenated blood to rest of the body. The co2 then leaves the lungs when you exhale. Hope this helped. :)

Explanation:

Answer: [SAMPLE RESPONSE] The two systems work together in several ways. First, the respiratory system brings oxygen in the air to the alveoli in the lungs. The circulatory system then delivers the oxygen to the cells. Second, the circulatory system picks up carbon dioxide from the cells and carries it to the lungs, where it is released when we exhale.

An active transport process by which a vesicle moves a large substance out of the cell is known as __________.

osmosis
endocytosis
exocytosis
diffusion

Answers

Answer:

I'm pretty sure it is exocytosis. Because exocytosis transports vesicles out of the cell through the plasma membrane. Remember it as "exo" = exit.

Answer:

C. Exocytosis

Explanation:

The first thing we notice is that the question says "active transport". Looking at the answer choices, we see that "osmosis" and "diffusion" are options.

However, remember that osmosis (the diffusion of water from high to low concentration) and diffusion (the movement of particles from high to low concentration) are both passive transport; in other words, they don't require an input of energy. So eliminate them.

Now look at endocytosis and exocytosis. "Endo" means "inner", so "endocytosis" means the cell is engulfing a substance and bringing it inside. However, we want the process where a substance is moved out.

"Exo" means "out", so "exocytosis" means to expel something. That matches here, so our answer is C.

An embryo refers to the early development stage with respect to the multicellular organism. The organism should be again produced se-xually. Moreover, the development of embryonic should be a portion of the life cycle just done after fertilization and continued via when the structure of the body is formed like tissues and organs.

The development of embryonic i.e. used for proof with respect to evolution should be related species that contain the same embroys.The similarities during the embryo stage of development among different animals are due to the expression of ancient genes.

These ancient genes have the same evolutionary origin, thereby they are homo-logous sequences. For example, fish embryos and human embryos express certain homo-logous genes in the embryos stage, thereby leading to the development of gill slit during this stage.

When a certain type of rock, specifically, an igneous rock, is deeper into the ground, and it is under the influence of high temperatures and pressures, it will start to change its molecular structure over time. In addition to the high temperature and pressure, chemical influences are also very important, so the the rock will gradually turn into a metamorphic rock.

 Depending on the type of influences, and their intensity as well, one type of rock can evolve into multiple different types of metamorphic rocks.

How can scientists investigate the impact of limiting factors on a population?

Answers

Answer: No population can increase without limitation. Instead, populations in natural ecosystems increase or decrease in response to the changes in the factors that restrict growth. Many factors influence population densities and growth, and these factors may lead to oscillations in population size over time. It is also often difficult to determine the exact factor limiting growth. Many different factors may combine to produce unexpected results.

Explanation: I hope this helps....

Answer:

Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration. Limiting factors determine the carrying capacity of a population.
