how does asexual reproduction limit variation in species?

Answers

Answer:

less of a chance for mutations

Explanation:

Answer:

Asexual reproduction is a cheap and fast method for producing large numbers of propagules having little diversity. The method of cell division is mitosis, which produces identical daughter cells. This is largely advantageous when survival of offspring is dependent, more upon explosive population growth, than on the diversity of each individual. Plankton species are such an example, where to survive they mostly just need to out produce predation.

Most organisms engage in sexual reproduction at some point in their life cycle to introduce diversity when survival is dependent on susceptibility to parasites. Host — parasite coevolution is an arms race accelerated by diversity.

In sexual reproduction, the method of cell division is meiosis, where diversity is introduced through crossing over, independent assortment, and also, random fertilization.

Enzymes lower the activation energy for a chemical reaction to proceed.

Answers

Answer:

The statement is true since one of the main functions of the enzyme is to lower the activation energy so that a chemical reaction to proceed.

Explanation:

Enzymes are specialized protein molecules that contribute to faster chemical reactions. One of the functional characteristics of an enzyme is that it reduces the activation energy for a reaction to occur.

Activation energy is the amount of net energy required for a reaction to occur. By lowering the activation energy, a reaction occurs faster, which is achieved with a biocatalyst such as enzyme.

Which of the following is an incorrect match? a. endocytosis – substances taken into the cell b. exocytosis – substances secreted from the cell c. pinocytosis – liquids secreted from the cell d. phagocytosis – large particles taken into the cell

Answers

Answer:

The correct answer is c.pinocytosis – liquids secreted from the cell

Explanation:

Pinocytosis is a type of endocytosis in which substances are internalized into the cell from the celullar exterior. The components are not secreted from the cell but are uptaken into the cell. This internalization process is characterized by the formation of an invagination of the cell membrane where then is formed a vesicle surrounding the component to be uptaken.

A. It conserves more fossil fuels.
B. It uses the same amount of fuel per person.
C. It uses more expensive fuel per person.
D. It uses more fossil fuels per person

Answers

Answer: A. It conserves more fossil fuels

Explanation:

This approach saves more fossil fuels than using lots of gasoline-powered cars, each with just one occupant.  So, the correct option is A.

What are Fossil fuels?

A fossil fuel is a hydrocarbon-containing substance that is recovered and used as fuel that naturally forms in the Earth's crust from the remains of dead organisms and plants. Fossil fuels include coal, oil, and natural gas. Fossil fuels can be burned to produce energy, drive engines, or provide heat for immediate use.

A general name encompassing non-renewable energy sources such crude oil, petroleum products, natural gas, derived gas, coal, coal products, and non-renewable wastes is "fossil fuel." These fuels are made from ancient geologically-dated plants and animals (for example, millions of years ago). Compared to using many single-occupant gasoline-powered cars, the method conserves more fossil fuels.

Therefore, the correct option is A.

You might then also realize that the new method, at least on paper, may have additional applications. ... which makes the technology attractive to yet more scientists.

Explanation:

Hoped I helped you out please mark me brainliest!!!

With the creation of the microscope, humans were able to observe plant and animal cells, and as technology advanced, scientists were able to learn more about these various types of cells.

What is a microscope?

A microscope is a device that can be used to examine small objects, including cells. The image of an object is magnified in the microscope by at least one lens.

In most cases, the light is focused on the sample by passing it through a condenser.

After passing through the sample, the light passes through the objective lens, which magnifies the image of the sample, and then to the oculars, where the enlarged image is viewed.

The discovery of the green fluorescent protein (GFP), the development of increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technological advances that have fueled many areas of cell biology.

Thus, it can be concluded that the advancements in technology help scientists better understand process of cell division.

Explanation:

The human blood group is classified into four major classes which are A, B, AB, and O. This is possible due to multiple allelism and codominance which are found in the alleles A and B.

What is blood typing?

A blood type is the classification of blood into different groups, based on the presence or absence of antibodies and inherited antigenic substances on the surface of the red blood cells which are present in the blood. These antigens may be proteins, carbohydrates, glycoproteins, or the glycolipids, depending up on the blood group system.

In humans, the blood typing is of four types that is A, B, AB, and O. This is because, the blood typing is an example of multiple allelism and codominance. A and B alleles are codominant and O is recessive.
