Diverse mammals developed and began to flourish in the Cenozoic era . Which of the following also began to develop and flourish during this time ?

The polysaccharide that is responsible for the strong structural nature of cell walls of plants is cellulose.

The cellulose is an organic molecule that is made up of several units of glucose monomer. The cellulose which make up a large percentage of plant cell walls are composed of a network of several units of glucose monomer that are tightly linked together.

The cellulose, as well as lignin and hemicellulose, which constitutes the tensile fibers in the cell walls of plants, is the polysaccharide responsible for the strong structural nature of plant cell walls.

Answer:

a) 0.1 mL

b) contamination

c) clumping of colonies

d) Uneven colonies

Explanation:

In general, when performing spread plates, 0.1 mL

mL of cell suspension is added to the plate to prevent the formation of a microbial contamination

Adding more than 1 mL of cell suspension to an agar plate will result in a clumping of colonies.

Adding less than 1 mL of cell suspension to an agar plate will result in a Uneven colonies

Answer:

the answer is the third one

Answer:

475

Explanation:

The strand is only made up of Adenine, Thymine, Cytosine and Guanine. There will be the same number of Adenine as there are Thymine and the same number of Cytosine as there are Guanine.

We know there are 425 Thymine. This means there are also 425 Adenine. Therefore, you would subtract 850 (425x2) from 1800 to find the amount of Cytosine and Guanine left, which is 950.

Out of the 950, half will be Cytosine and half Guanine. 950/2 is 475.

Answer:

Explanation:white moths will be spotted easier and killed and the population would drop while the dark moths population will rise

The population of white moths at the light tress will increase over time with the process of natural selection.

The trees are a light color population. Dark moths are unable to camouflage with the tress, while white moths camouflage with the trees.

The white and black moths at the tree are an example of a tree ecosystem. The moths are the target for the predators.

The process of natural selection is the evolutionary process with the survival of the fittest. The species that are able to survive in the inappropriate conditions are able to evolve.

In the tree ecosystem, the white moths are camouflaged with the trees. They will not be an easy target for predators. They will survive with the theory of natural selection.

The black moths are not camouflaged with the tree ecosystem. They are easily identified by the predators and are killed.

Thus, white moths are the fittest and with natural selection, they evolve.

Therefore, the population of white moths at the light tress will increase with natural selection.

Answer:

Mutation is any change in DNA sequence of an organism. Mutantion can occur in any living organism including plants, animals, fungi, bacteria and protists.

Explanation:

Explanation:

Advantages Of the asexual reproduction

The organism that reproduces asexually has the ability to take many different extensive forms that allow asexual reproduction to succeed in various environments?

The asexual reproduction is only performed in the organisms that often stay in one place, It does not need mobility, So, most plants have a great ability to create their offspring as this process doesn’t need to move to another place.

Asexual reproduction has a rapid increase of offspring which is very helpful in producing lots of offspring, It lets the plants make lots of offspring effectively which will help them in increasing their genes.

Disadvantages Of Asexual Reproduction

Most organisms that only perform the asexual reproduction process have less chance to adapt to the changes of the environment as they need stable environments.

Only one parent plant is required for the asexual reproduction, the new plants are identical to the parent so that good features will always be passed on, the chromosomes and genes of the parent will be copied, So, there will be genetic defects or the mutation in the offspring with no exception.

The asexual reproduction does not have the genetic diversity, there is less variation produced with the offspring, and the organism becomes less adapted to certain environmental changes, the entire communities will not be adapted to the harsh environment.

The asexual reproduction usually leads to struggle for the existence as well as the overcrowding, and the main distinction of asexual reproduction from the sexual reproduction is that there is no need for two parents as well as special cells to reproduce.

Answer:

A

Explanation:

Cancer is the uncontrolled increase of cells, so when the rate of mitosis increases, so does the number of cells. This means A is the answer.

Uncontrolled cell growth is cancer. Gene mutations can increase the pace of cell division or suppress natural mechanisms that keep the body in check, like cell cycle arrest or programmed cell death. Thus, option A is correct.

The cell's size, the presence of neighboring cells, and other chemical stimulators are three of the key elements in mitotic regulation.

Numerous mitogens are involved in regulating mitosis. Therefore, cell size, cell existence, and chemical stimulators are the proper answers.

When cancer cells develop in body tissues, they undergo aberrant cell growth patterns known as hyperplasia and dysplasia.

An increase in the quantity of cells in an organ or tissue that look normal under a microscope is known as hyperplasia.

Therefore, An abnormal and uncontrolled increase in the rate of mitosis is frequently associated with an individual developing cancers.

1. Ozone

Explanation:

Ozone is a substance with the chemical formula, O3, found in the stratospheric part of the atmosphere. It functions to prevent the harmful ultraviolet (UV) radiation from the sun from reaching the Earth. However, due to anthropogenic activities i.e. human activities that releases greenhouse gases e.g. CO2, CFC etc. the protective function of the ozone layer is wavering.

Hence, based on this question, people are concerned over the fact that this OZONE layer is depleting, hence, risking the exposure to the harmful radiation from the sun.

Answer:

new adaptations come from:

New combinations of genes from parents.

Mutations in the DNA passed on to an organism.

Explanation:

Mutations in the DNA passed on to the organism and bring adaptations in the form of new characteristics. mutations may b lethal or fruitful and develop new characteristics in an organisms and increase its survival.

new combinations of genes from parents results from crossing over and recombination. these new genetic combinations bring adaptations.

Answer:

Ecological niches allow species to exist in their environment. Under the right conditions, the species will thrive and play a unique role. Without the ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.

If two species occupied the same niche, they would be competing for the exact same resources. The competitive exclusion principle states that one of the species would drive the other to extinction.
