Answers

Answer 1

Answer:

D. Oxygen is DEPLETED

Explanation:

iT NEEDS OXYEN TO SUSTAIN IN A CLOSED ENVIRONMENT

Answer 2

A sealed ecosphere is able to constantly continue life until oxygen is depleted. The correct option is A.

What is a sealed ecosphere?

A sealed ecosphere is a name given to a sealed ecosystem designed and made by Ecosphere Associates, Inc. These are miniature ecosystems in glass containers.

These miniature ecosystems continuously need oxygen to survive, because it contains small plants or mosses, or algae to grow inside.

Thus, option A. Oxygen is depleted is correct.

Suppose you traveled back in time and located the first animals to have evolved feathers. You found that these animals were tree-dwelling ectotherms, able to run quickly but unable to fly. You also noticed that only males had feathers. Which hypothesis of feather evolution would these data most support? Feathers initially evolved in a role associated with ________.

Answers

Answer:

Feathers initially evolved in a role associated with sexual selection.

Explanation:

In species where only males had feathers, these feathers can be considered to have evolved into a role associated with sexual selection. This is because in these species, males used their feathers as a sexual attraction for females, in this case, females chose the males that had more attractive feathers to mate and generate new individuals for the species. An example of this can be seen in the peacock, where the tail with lush feathers is only present in males and is intended to sexually attract females.

We pay attention while sound waves journey thru the air to our eardrum, throughout our center ear, into our internal ear, and sooner or later to the auditory facilities of our brain. Our ears are constantly on and are constantly sporting sounds alongside this listening-to pathway.

Which is an example of genetic drift?

Answers

Answer:

Explanation:

Genetic drift, gene flow, mutations, and natural selection are responsible for the change in the gene pool over time. Example of genetic drift: a population of rabbits with alleles B and b, both alleles are present in equal frequencies p = 0.5 and q = 0.5 if 10 parents reproduce the probability of having an offspring with alleles B or b is 0.5; however, by chance, a slight difference in the offspring allele frequency might occur due to random sampling. As a result, in the next generation, the allele frequencies will change slightly to new frequencies by chance to become p = 0.4 and q = 0.6. in the following generations, the random sampling of alleles continues and the change in allele frequency will be greatly different from the initial 0.5 frequency due to genetic drift. Even though genetic drifting is one of the factors that participate in the evolutionary process of the genetic pool by increasing or decreasing a certain allele’s frequency, however, it does not influence the adaptation of individuals to the environment since the affected genes may be harmful or beneficial genes.

Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three "dominant" capital letter genes (A, B and C) control dark pigmentation because more melanin is produced. The "recessive"alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced.

Here, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

What is Punnett Square?

The Punnett square is a tool used to predict the probability of offspring inheriting specific alleles from their parents. If all of the offspring exhibit the same phenotype (such as purple flower color), it is likely that the parents both carried at least one dominant allele for that trait. This would mean that the purple flower color allele is dominant. Here, the parents are both purple and white, so all the offspring are dominant in nature.

Hence, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

If the disaster such as earthquake and pandemic etc occurs in the neighbourhood so it also affected the health of the people of that region as well as the people that lives in the neighbourhood.

B. They can absorb both sunlight and moonlight .
C. It is not a benefit.
D. If one becomes damaged, the other can take over.

Answers

Answer:

Carotenoids have two important functions in plants. First, they can contribute to photosynthesis. They do this by transferring some of the light energy they absorb to chlorophylls, which then use this energy to drive photosynthesis. Second, they can protect plants which are over-exposed to sunlight. but the letter answer I don't know

The benefit of a plant having Chlorophyll and Carotenoids is that plant can absorb energy from multiple wavelengths at once. Option A is the right answer.

What are chlorophyll and carotenoids?

Chlorophyll is the green pigment that is responsible for the green color in the leaves of plants. Carotenoid on the other hand is a yellow, orange, and red color pigment that is produced in plants, algae, and some other forms of bacteria.

Chlorophyll actively absorbs light from wavelengths in the range of blue to red.Chlorophyll poorly absorbs light from the green range.Hence, carotenoids absorb light in wavelengths that are ineffective by chlorophyll such as the blue-green range to green range.

Answers

Answer:

is a thick band of neural fibers enabling communication between the two brain hemispheres.

Explanation:

A brain can be defined as an organ of soft nerve tissue that is found in the skull of vertebrates and it's typically responsible for the coordination of nervous activities, intellect and sensation.

The human brain consists of various sections and these includes;

I. Anterior Cingulate Cortex (ACC) which resembles a bow or collar surrounding the frontal part of the corpus callosum. This is the frontal part of the cingulate cortex which helps to make complex cognitive functions such as impulse control, decision-making, emotions and empathy.

II. Ventral prefrontal cortex in humans are interconnected with the brain and are responsible for the processing of risk, empathy, fear and social decision-making

III. The Cerebral Cortex: this part of the brain primarily comprises of grey matter, foldable sheets of neurons and forms its outermost layer. Therefore, cerebral cortex is known as the outermost layer of the brain (cerebrum) and thus, makes up half of its weight. It is about 2.5 millimeters in thickness and as such it's able to fold.

The corpus callosum is a large, thick band of C-shaped neural fibers found beneath the cerebral cortex and it's saddled with the responsibility of enabling communication between the two brain hemispheres i.e the right hemisphere and the left hemisphere.

Answers

Answer:

2. Parathyroid hormone level decreases

4. Ca and phosphate reabsorption decreases

Explanation:

When plasma Ca concentration decreases, the action of Parathyroid hormone level decreases  which leads to Calcium and phosphate reabsorption decreases. Parathyroid hormone is responsible for the increase of calcium and phosphorus in the blood when there is low level in the blood so when the re is huge amount of calcium and phosphorus in the blood, the Parathyroid hormone activity decreases which decrease the reabsorption of calcium and phosphorus decreases.
