Answer:
No oxygen is required.
Explanation:
This pathway for forming ATP needs no oxygen and the ATP that is produced are in very low concentration. The low amount of ATP production occurs when the cell goes for anaerobic respiration in which the cell produces less ATP. This type of ATP production occurs only when the body requires ATP quickly so that's why the body uses this type of respiration during exercise and running activities etc.
The circled portion of DNA labeled X in the following picture is a
a phosphate group
b sugar
c nucleotide
d aldehyde base
Answer:
a. Phosphate group
Explanation:
The circled portion of the DNA labeled X is ; ( C ) Nucleotide
The Nucleotide in a DNA molecule is the building block of the nucleic acid and it consists of a sugar molecule, A phosphate group ( P ) and nitrogenous base like adenine, cytosine or guanine.
The circled portion covers a nitrogenous base ( cytosine ), a phosphate group and a sugar molecule therefore the circled portion correctly represents a Nucleotide in a DNA molecule.
Hence we can conclude that the circled portion of the DNA is Nucleotide.

The top two human activities that threaten the habitats of endangered species globally are:
a.) Over-exploitation and agriculture
b.) Urban development and invasion of non-native species
c.) System modification and war
d.) Pollution and climate change
Answer: D
Explanation:
plant breath through
Answer:
Plants respire through plant pores, called stomata. During respiration and photosynthesis, gases go in and out of the plants through stomata using diffusion, not breathing.
Answer:
respiration
Explanation:
Plants breathe through a process called respiration, where they exchange gases between the outside and the inside of their bodies as a living organism. They breathe through openings called stomata. Photosynthesis makes a plant produce oxygen, but a plant also requires oxygen constantly.

Question 5
Where do new adaptations come from? There is more than one correct answe
choose all that apply!!
New combinations of genes from the parents
Nature will give an organism the adaptations it needs to survive
An organism can choose to grow an adaptation
Mutations in the DNA passed on to an organism
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.

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

Why are niches important to
ecosystems?
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.

Since Asha is a healthy woman in her fortles, she does not have Niemann Pick
disease type A. For this question, assume that she is a healthy person who is a
carrier. If Asha is a carrier of the allele for Niemann Pick disease type A, what is het

Answer:
By the definition of "carrier," Asha does not exhibit any physical features (phenotype) of the Nieman-Pick disease, but she carries an allele for this disease. In order for this to be possible, Asha must carry a autosomal dominant allele for this gene to mask the effects of carrying an allele for the.

Over time, what will to happen to the populations of light and dark moths on light trees?
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.
What happens to white moths?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.

A model showing two possible arrangements of chromosomes during meiosis is shown in Figure 1.Figure 1. Two possible arrangements of chromosomes during meiosis
Which of the following questions about genetic diversity could most appropriately be answered by an analysis of the model in Figure 1?
A) Does crossing-over generate more genetic diversity than the fusion of gametes does?
B) Does DNA methylation prevent independent assortment during metaphase II?
C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?
D) Do daughter cells that are not genetically identical to parent cells produce viable zygotes?
C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?
What is independent assortment?Independent assortment is a mechanism that contributes to genetic diversity during meiosis. It refers to the random alignment and separation of homologous chromosomes during the first meiotic division (meiosis I), which leads to different combinations of chromosomes being passed on to the daughter cells.
This means that each daughter cell will have a unique combination of chromosomes. When the gametes (sperm or egg cells) produced by meiosis fuse during fertilization, they can give rise to offspring with a unique combination of genetic information, further increasing genetic diversity within a population.

Approximately 75% of the Earth's surface is covered in water. Why is water considered such a precious resource?
Answer:
Water is precious since it is one of the most basic commodities that sustain the life of human beings, animals and plant. Without water, it would be impossible for any form of life to exist in the universe. Close to 75% of the Earth is covered with salt water, while 2% of the surface contains frozen water.
Explanation:
Why is water a precious resource?
It is needed for all living things and must be managed well to ensure we have enough for our needs and to protect our environment. Water is a precious resource. We can't live without it. Clouds formed by this vapor ensure that water falls back down to Earth as rain, sleet, snow or hail.Water resources are sources of water that are useful or potentially useful to humans. It is important because it is needed for life to exist. Many uses of water include agricultural, industrial, household, recreational and environmental activities.
