Answer:
A. They do not use up any energy finding mates.
Explanation:
The asexual reproduction consists of one parent which are same to each other while on the other hand consists of two parent that produced unique.
For species survival, the reproduction of protozoa asexually rather than sexually could be better when they don't use much time and energy for determining the mates
Therefore in the given case the correct option is A.

Smurfs live in widely separated groups and rarely interbreed, so geneticists know very little about them. On one occasion, two smurfs from different groups did mate. A big-footed, white smurf mated with a small-footed, blue smurf. Three offspring resulted: one big-footed and blue and two small-footed and blue.Which statement about the inheritance of color in smurfs is most likely to be correct?
Answer:
See the answer below
Explanation:
The most correct statement would be that the blue color is dominant over the white color.
According to Mendelian law, when there are two different versions of the same gene/trait in which one is dominant and the other is recessive, the dominant version will be expressed while the recessive version only stays in the background.
In this case, the alternate versions of the same trait in the smurf are the white and blue colors. When they are mixed together in the offspring, the blue color is expressed and the white color stays in the background. It means the blue color is dominant over the white color.

Q. Habitat loss occurs due to agriculture, forestry, and other human activities. Describe the effect of these activities on species diversity in the ecosystems in which they occur, and how this would affect the stability of these ecosystems over time.
Answer:
Explanation:
Human activities had led to diversity of species in ecosystem. Some of the species of animal have been lost and displace due to human activity such as deforestation, construction, company establishment.
Clearing of land for agriculture use has also contributed to diversity that occur in the habitat of an animal.
Diversity of an habitat leads to an unstable ecosystem, as animals can no longer thrive and live in their environment, some species of animals are lost including important species in the environment in the process and others struggles to survive.

Explanation:
acteriophages were labeled with radioactive phosphorous (32P) and sulfur (35S). The labeled bacteriophages were then allowed to infect their host cells. At the end of the experiment, the 32P label was found only inside the host cells and the 35S label was found only outside the host cells. This experiment shows that:
Answer:
They concluded that DNA is a genetic material.
Explanation:
This experiment shows that the DNA is genetic material. For performing experiments, the DNA of bacteriophages is labelled with radioactive phosphorous (32P) and proteins were labelled with sulfur (35S) in order to detect the action of bacteriophages. The bacteriophages attack on the bacteria by inserting its DNA in the bacteria. We can see this because radioactive phosphorus is present in DNA of bacteriophages while the protein did not enter into the bacteria and remain outside the cell and we can see it because protein is made up of sulphur.

Lipids provide about
kJ/g of energy and are stored in
A. 19, granules
B. 36, triglycerides
C. 38, adipose tissue
D. none of these is correct
Answer:
C. 38, adipose tissue
Explanation:
Lipids/fats are one of the three energy storing biomolecules in living systems; the other two being carbohydrates and proteins. Three of them supply energy when oxidized but the amount of energy differs with lipids providing the most amount of energy.
Lipids provide 9 calories of energy per gram when oxidized, which is about 38Kj/g (where 4.2kJ = 1 calorie). Also, lipids or fats are stored throughout the body, specifically in connective tissues called ADIPOSE TISSUES.

After getting the slide and microscope ready, Stella is eager to see the microscopic pond water specimen! She crouches around her microscope and aligns her eye with the microscope’s eyepiece. But she's only able to see a bright white light. At this point, no specimens or cells are visible on Stella's pond water slide. After taking a moment to collect her thoughts, Stella realizes she can't see any lifeforms because a.the microscope is not yet in focus b.the microscope is not plugged in c.there are no specimens on the slide d.she hasn't fastened the slide to the stage
Answer:
she hasn't fastened the slide to the stage
Explanation:
In Microscopy even if the slide is not yet in focus,she will be able to see part of the slide which may appear as transparent image.Therefore this is a wrong answer.
If the microscope is not plugged it light can not come up.
If there are no specimen on the slide,the slide will still as transparent image at the focus.
No doubt Stella forgot to fasten the slide to the stage.,therefore the specimen on the slide was not in focus of the objective lens,rather she was focusing on the stage only,hence the visible white light.
Students make these mistakes in microscopy,they sometimes place the slide on the stage,but forget to fasten the stage clip,thus the slide is not in focus of the incident light,which gives no reflection to the viewer's eyes.

What is the basic purpose of cellular respiration? What are the reactants and products of cellular respiration overall? Also, give a basic description of the three main stages of cellular respiration (glycolysis, Kreb cycle, and the electron transport chain)
Answer:
The Main basic purpose is to be able to breath and live. Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.The three main stages of cellular respiration (aerobic) would include Glycolysis, the Krebs Cycle and the Electron Transport Chain. The Krebs Cycle takes Citric Acid which is a derivative of Pyruvic Acid and converts this through 4 cycles into Hydrogen, carbon dioxide and water in the Mitochondrial Matrix.
Why don’t populations of organisms that reproduce asexually have the same genetic variation as populations that reproduce sexually
Answer:
Asexual reproducing populations only get their genetics from a single parent, meaning that they all have the exact same DNA/RNA, while sexually reproducing populations have two parents meaning they get genetic code from two parents instead of one, therefore they have more variance. This variance is also the reason sexually reproducing populations are usually harder to wipe out due to variance.
What is true about the most recent ice age?
O A. All life on Earth became extinct.
O B. It occurred during the Precambrian era.
O C. Sea levels rose over 300 feet.
D. Land bridges existed that are now underwater.
The truth about the last ice age: D. There was now a submerged overpass.
An ice age also called an ice age, is a geological period in which thick ice sheets cover vast land areas. These massive ice ages could last for millions of years and could radically change the surface topography of entire continents.
There have been several major ice ages in Earth's history. The amount of sunlight reaching Earth over thousands of years varies considerably, especially at the North Pole and its surrounding northern latitudes. When less sunlight reaches northern latitudes, temperatures drop, more water freezes into ice, and the Ice Age begins. This ice age began about 2.6 million years ago in a period known as the Pleistocene epoch and lasted until about 11,000 years ago. Like everything else, the Last Ice Age brought about a series of glacial advances and retreats. In fact, we are technically still in the Ice Age.

What is adaptation?
Adaptation is a long-term or short-term change or modification of the body to survive and match the environmental conditions. Adaptation is necessary for every organism to increase its population.
Adaptation is categorized into different types according to the places where animals and plants live. Examples of adaptation are desert plants having thick leaves or no leaves to save water, and snow animals being white to blend in.
The animals living in very cold regions, like the arctic and Antarctica, have white fur to blend with the environment and save from predators.

2. How might a mutation that causes a single letter change in the DNA sequence affect
your protein structure and function?
Answer:
A mutation that causes a single letter change in the DNA sequence can affect your protein structure and function because the sequence of letters in a gene determines the sequence of amino acids in the protein that it encodes. A single letter change in the DNA alters the mRNA which alters the amino acid sequence of the resulting protein and sometimes that can cause serious results if it changes the way a protein works.
ex. sickle cell disease - a single letter swap in the gene that encodes the hemoglobin molecule results in deformed red blood cells

Why do droughts contribute to desertification?
Answer:
Drought and desertification are firmly related phenomenon. Continuing over months or years, drought can influence enormous zones and may have genuine ecological, social and financial effects.
While drought is a characteristic phenomenon, whose effects can be exacerbated by human exercises that are not adjusted to the neighborhood atmosphere, land debasement is the way toward transforming fruitful land into less or non-gainful land. In extraordinary cases in drylands this is called desertification.
Land debasement and desertification are complex phenomenon driven by un-adjusted human action in mix with land and climatic requirements. Improper land use, for example, monocultures, and unreasonable land the board rehearses, for example, deforestation, unsatisfactory agrarian practices and overexploitation of water assets), can cause land debasement that can be additionally disturbed by drought.
Which of the following statements associated with cellulose is false? A) It's a linear polymer of glucose. B) The glycosidic linkage is β(1 → 4). C) Hydrolysis is accomplished enzymatically by cellulase. D) Most animals can easily digest this compound.
Answer:
Most animals can easily digest this compound
Explanation:
Cellulose is a linear polymer of glucose comprising of beta 1,4-glycosidic linkage of glucose molecules; this is where it differs from starch. Cellulose is a polysaccharide made of glucose monomers just like starch. The enzymatic hydrolysis of cellulose is achieved by the enzyme cellulase.
Not all animals can digest cellulose. As a mater of fact, no vertebrate can digest cellulose directly. Many herbivorous animals possess symbiotic bacteria in their gastrointestinal tract which enables the digestion of cellulose. These bacteria possess the requisite enzymes for the digestion of cellulose.
