What are some of the negative effects of asexual reproduction? Topic sentence 1 point Body (two or three reasons) 2 points Conclusion Sentence 1 point

Answers

Answer:

In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.

The disadvantages of asexual reproduction include:

it does not lead to genetic variation in a population. the species may only be suited to one habitat. disease may affect all the individuals in a population.

Explanation:

Answer:

One disadvantage of Asexual Reproduction is that organs do not receive a mix of trait from both parents. An organism that is born through Asexual Reproduction only has their DNA from the one, and only, parent. The offspring is genetically an exact replica of their parent. The child born through Asexual Reproduction could possibly look exactly like his or her parent! Cool right?

Pls help

Answers

The components that are found in the cells of all living organisms from the available options are Cytosine and Guanine.

All living cells contain important biomolecules such as lipids, proteins, nucleic acids, etc.

Nucleic acids are made of 3 major components:

pentose sugarsphosphate groupsnitrogenous bases

The nitrogenous bases could be:

purines: such as Adenine and Guaninepyrimidines: such as Cytosine and Thymine or Uracil

Thus, by all means, no living organisms can do without possessing Cytosine and Guanine because all living organisms have nucleic acids.

Why or why not? Explain using the meaning of abiotic and your understanding of the characteristics of life.

Answers

Answer:

Abiotic factors are nonliving.

Living things have cells.

Abiotic factors cannot have cells.

The non-living element of the ecosystem which creates the background is called abiotic factors.

Abiotic factors are important because they influence the life cycle of the ecosystem.

Abiotic factors are non-living:

They are the determinants that do not have specialities like a living thing and comprises water, mountains, light, temperature etc.

Breathing objects are made up of structural units called cells but abiotic constituents lack cells.

Abiotic factors cannot give birth and hence are not generative.

They are not competent in using the energy needed for metabolism.

Therefore, abiotic factors are non-living.

Scientists have found that the Uranium-235 content of an unknown prehistoric sample was reduced to one-fourth. What best describes the identity of the sample?

A stone artifact that formed 700 million years ago
A mammoth that died 1,400 million years ago
A cliff that formed 1,400 million years ago
A plant that died 700 million years ago

Answers

Answer:

Half-Life is the time for a substance (U-235 in this case) to decay to 1/2 its original mass.

Since the problem is asking for the time for U-235 to decay to 1/2 its original mass (100 grams to 50 grams) then the decay time is 1 half-life, or 700 million years.

Describe the process of digestion in written form.

Answers

Mouth. To more easily absorb different foods, your saliva helps break down what you're eating and turn it into chemicals called enzymes.

Esophagus

Stomach

Small Intestine

Large Intestine, Colon, Rectum and Anus.

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion like the tongue, salivary glands, pancreas, liver, and gallbladder.the Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.

Our body needs food to provide it with energy, vitamins, and minerals. However, in order use food, we must first break it down into substances that the various organs and cells in our body can use. This is the job of our digestive system. The digestive system acts in stages to digest our food. Each stage is important and prepares the food for the next stage. The entire length of our digestive system is around 20 to 30 feet! Here are the major stages of the digestive system:

1. Chewing - Chewing is the first stage of the digestive system. When you chew your food it breaks up big pieces into little pieces that are easier to digest and swallow. Also, your saliva is more than just water. It has special enzymes in it that start to break down starchy food (potatoes, bread) while you chew.

2. Swallowing - Swallowing may seem like a simple process to us. It just sort of happens. But food doesn't just fall down our throats into our stomach. First, our tongue helps to push food into the back of our throat. Then there are special throat muscles that force the food down into a long tube that leads to our stomach, called the esophagus. The food doesn't just fall down the pipe, muscles push the food along until it gets to our stomach. At the same time all this is going on, a flap blocks off our windpipe making sure food doesn't go the wrong way. We call this "going down the wrong pipe" and it can make us choke. This flap is called the epiglottis and, fortunately for us, it works automatically.

3. Stomach - The next stage is the stomach. Food hangs out in the stomach for around four hours. While the food sits there, more enzymes go to work on it, breaking down things like proteins that our bodies can use. The stomach kills a lot of bad bacteria as well, so we don't get sick. 4. Small Intestine - The first part of the small intestine works with juices from the liver and pancreas to continue to break down our food. The second part is where the food gets absorbed from the intestine and into our body through the blood.

5. Large Intestine - The last stage is the large intestine. Any food that the body doesn't need or can't use is sent to the large intestine and later leaves the body as waste.

6.The Liver and Pancreas The liver and pancreas do a lot to help the digestive system along. Both work with the small intestine. The liver provides bile (stored in the gall bladder) that helps break up fat into smaller bits. The pancreas provides additional enzymes to help digest all sorts of food. The liver also processes the digested food from your blood before it gets sent to various places in your body to be used.

What is the difference between sample count
and total count?

Answers

Answer:

A sample count is the data from a sample, or a small group. A total count would be the data from the entirety of whats being studied, not just a sample.

A lot of researchers often perform a total count or a sample count in research. The difference between sample count  and total count is that a total count is done when the whole study area is surveyed but a sample count is done only when parts of the study area are surveyed.

The results obtained from those parts are used for the whole study area to approximately know the total population size.

Wildlife sampling methods often uses different methods of estimating animal numbers or densities. they are direct counts of population units, and indirect counts and indices.

Wild animals are very difficult to count as all  animals are never distributed evenly within the sample area and there may be fluctuations.
