Answer: Biodiversity is the variety of life, which is responsible for ensuring the balance of ecosystems around the world. It provides necessary goods such as food or oxygen, it provides raw materials that favor economic development, it produces energy that we use as fuel, and it is the origin of some medicines. If all animals in an ecosystem were of the same species, the balance would be lost.
Explanation:
An ecosystem is a set of living beings (of different species) that share the same habitat or biotope. There are first of all primary producers, those that are capable of producing organic matter from inorganic compounds. These organisms are autotrophs, such as plants. Then we find in the second step the consumers, heterotrophic organisms (herbivores, carnivores or omnivores) that feed on matter and energy produced by other living beings. And in the last link of the trophic chain of organisms that make up an ecosystem we find the decomposers, those that feed on dead organic matter. In this way, there are complex interactions between different organisms of different species.
Thus, biodiversity is the variety of life, which is responsible for ensuring the balance of ecosystems around the world. It provides necessary goods such as food or oxygen, it provides raw materials that favor economic development, it produces energy that we use as fuel, and it is the origin of some medicines.
If all animals in an ecosystem were of the same species, the balance described above would be lost. If they were all producers like plants, there would be no consumers to control the plant population. If they were all consumers, they would eventually run out of food. And if they were all decomposers, they would not have enough dead organic matter to feed on either. A greater number of species or biological diversity in an ecosystem makes it more resilient. Because species can absorb and reduce the effects of environmental changes on the overall structure of the ecosystem. In addition, they can reduce the chances of a change to a different state.

In mice, black color (B) is dominant to white (b). At a different locus, a dominant allele (A) produces a band of yellow just below the tip of each hair in mice with black fur. This gives a frosted appearance know as agouti. Expression of the recessive allele (a) results in a solid coat color. If mice that are heterozygous at both loci are crossed, ___ out of 16 will be black in color.
Answer:
3
Explanation:
Heterozygous mice at both loci would be BbAa genotype.
B (black) is dominant over b (white) but the presence of A results in agouti.
Crossing two heterozygous:
BbAa x BbAa
Progeny
9 B_A_ - Agouti
3 bbA_ - agouti
3 B_aa - Black
1 bbaa - white
Hence, 3 out of 16 progeny will be black in color.

Answer:
Use the Weather probeto measure the land-air and ocean-air temperatures. What are these temperatures at this time? 29.1 degrees and 22.2 degrees, respectively. C.
Explanation:
By using the Weather probe to measure the land-air and ocean-air temperatures. It is found that the temperature of land air is found be 29.1°C and the temperature of ocean air is found to be 22.2°C.
What is a weather probe?A weather probe may be defined as an observation post where weather conditions and meteorological data are considerably observed and recorded under controlled conditions. While weather governs the state of the air and atmosphere at a particular time and place.
According to the context of this question, a weather probe determines a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate.

TRUE OR FALSE: DNA sequences are exactly the same for organisms that are related to each other. (If false please explain).
Answer: False
Explanation:
DNA sequences can be similar for organisms that are related to each other but through various steps of meiosis like crossing over and law of independent assortment we can get genetic variations that lead to slight differences. We can also get differences in DNA sequences due to mutations.

Why are trees generally measured at 4 feet, six inches feet from the ground?
Answer:
Trees are generally measured at 4 feet, six inches feet from the ground because trees are generally a bit wider at the bottom where the roots begin to spread, so choosing a point at which all trees are measured is one way to keep documentation consistent. 3.

What are the causes of variations ? please explain thi also
Answer:
variation can be caused by mutation and other things
Explanation:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light or cigerette smoke
➜ Following are the causes of variations:
Dual percentage: Offsprings inherit some features from mother and some from father. Hence no offspring will exactly resemble to either of the parent or each other.Mutation in gene or chromosomal pattern also causes variations.Your normal heartbeat before exercise is called your ____________________.

how will photosynthesis affect oxygen levels?
(also if anyone could help me with the rest of these answers, that would be great <3)
The process of photosynthesis positively affects the level of oxygen in the ecosystem. This is because oxygen is the byproduct of the photosynthesis mechanism along with the main product known as Glucose.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis si as follows:
[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O.[/tex]With the help of this reaction, this is determined that if the rate of photosynthesis increases, the level of oxygen is positively affected which means it is also increasing. It is opposite to the process of cellular respiration which involves oxygen as a reactant.
Therefore, the process of photosynthesis positively affects the level of oxygen in the ecosystem.

How did New Zealand's early ecology affect which traits were selected for/against in the kakapo's ancestors?
Answer:
Hairy skin which helps kakapo's ancestors to live in harsh climate of New Zealand.
Explanation:
New Zealand's early ecology greatly affected the population of kakapo's ancestors because the environmental conditions for kakapo's ancestors are favourable and there is no invasive species which reduces the population of kakapo's ancestors near to extinction. The traits that were selected for the kakapo's ancestors provides ability to live and survive in the temperate and subtropical climates of New Zealand. The flightless trait in this bird is also responsible for its extinction because this bird can't run away from their predators.

Human Immunodeficiency Virus (HIV) is a virus that infects (and destroys) Helper T Cells. As a result, people who are HIV+ generally have a low number of these T Cells. How would the dramatic decrease in Helper T Cells caused by HIV affect a person’s immune response? Be specific using details from what you learned about the immune response.
Answer:
HIV invades various immune cells (e.g., CD4+ T cells and monocytes) resulting in a decline in CD4+ T cell numbers below the critical level, and loss of cell-mediated immunity − therefore, the body becomes progressively more susceptible to opportunistic infections and cancer.
HIV infects and deletes CD4+ T cells that normally coordinate the adaptive T- and B-cell response to defend against intracellular pathogens. The immune defect is immediate and profound: At the time of acute infection with an AIDS virus, typically more than half of the gut-associated CD4+ T cells are depleted, leaving a damaged immune system to contend with a life-long infection.
