Few plants can survive in a desert because
A.There are many herbivores B.The sun is too hot
C. The climate is too dry
D. Too much leaching occurs
Answers
Answer: C
Explanation: If you were to travel to the desert, the only plants you would find would be shrubs and cacti, because unlike most plants, they are able to survive in a dry climate with very little water. All plants need the basics- that is, sun, water, and CO2, but only a select few have been able to adapt to the harsh desert climate. There are other places in the world where there is intense sunlight all day, (like my front yard, for example, which is ALWAYS yellow smh) but the plants usually are okay as long as they get enough water, which my grass doesn't lol.

The genotype of an organism must therefore be homozygous recessive if it exhibits a recessive characteristic in its phenotype. Examples: If we come across a white guinea, its genotype should be “bb”.
What is the genotype of the guinea?A phenotype with juvenile hairlessness, weak skin, and age-dependent lung emphysema has been identified. The three genotypes may be distinguished, and the characteristic exhibits autosomal co-dominant inheritance.
The dominant allele H in guinea codes for the trait of having hair, whereas the allele H codes for the trait of not having any hair.
The guinea with the black coat is homozygous for the dominant allele if all of his or her progeny have black coats (BB). Heterozygous hybrids occur when guinea with black coats produce offspring that are half black coat color and half white coat color (Bb).
Therefore, it is false that the guinea you would be able to tell if its genotype were HH or Hh.

Antibiotic resistance can vary within a population of bacteria. The diagram below represents the changes in a population of bacteria as a result of exposure to antibiotic over time.
Explain how this is an example of natural selection, and why we can use this as evidence that evolution occurs.
Answers
Answer:
The resistance that some bacterial populations develop to an antibiotic is an example of natural selection because the individuals with more resistance are those that survive, being an evidence of evolution since resistance can be inherited to the following generations.
Explanation:
The resistance to antibiotics that bacteria develop is the best example of how natural selection and evolution occurs, especially because of the fast and easy reproduction of these microorganisms.
In the example it can be seen that only the the most resistant bacterial populations to the antibiotic survive over time. Antibiotic resistance is due to mutations developed by bacteria that modify their structure and function so that they are not affected by an antimicrobial. According to natural selection, these mutations make resistance an inherited trait, and future generations will not be sensitive to the effect of the drug.
Why does natural selection occur? Only resistant individuals survive the effect of the antibiotic.
How do you explain evolution? Successive generations of bacteria have evolved, through mutations, to resist the effect of an antibiotic.

Explanation:
V Common Cold
B Tooth Decay (resulting in root canal)
B Strep Throat
V Influenza (“flu”)
Strep throat is caused by streptococcus which is a bacteria. They are present but can grow in numbers due to other problems in the body.
Tooth decay is caused by bacteria and that is why we should avoid feeding them with sweets so they don't grow in numbers.
Influenza is a virus that causes the flu. We have a flu season each year and a vaccine against it.
The common cold is also caused by a virus and there are a few of them that cause the same kinds of symptoms.

Which best explains why plants and animals need nitrogen?
Answers
Answer: Nitrogen is important to all organisms because it forms the basis of many compounds necessary for life. However, living things cannot use N2 in its gaseous form in the atmosphere. Nitrogen gas found in air pockets within soil is converted into a form usable by plants through a process called nitrogen fixation.All plants and animals need nitrogen to make amino acids, proteins and DNA, but the nitrogen in the atmosphere is not in a form that they can use. ... When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.

Thirty corn seedlings of equal size were randomly assigned to one of three treatment groups. At the beginning of the experiment, the plants in group I were dried and the mass was determined. The plants in group II were maintained in light for a week. The plants in group III were maintained in the dark for a week. All conditions, other than light, were the same for groups II and III. At the end of the week, the plants in groups II and III were dried and the mass was determined.
To explain the increase in mass of the light-grown plants, identify ONE inorganic source of new plant mass and connect it to the cellular process underlying the increase in mass.
To explain the decrease in mass of the dark-grown plants, identify the overall chemical reaction that is occurring in the plant cells and connect it to the cellular process underlying the decrease in mass.
Answers
Answer:
See the answer below
Explanation:
To explain the increase in the mass of the light-grown plant, one inorganic source of new plant mass would be carbon from carbon dioxide. The carbon becomes fixed into the plant through a process known as photosynthesis. During this process, carbon dioxide combines with water in the presence of light to produce carbohydrates, a major component of plant mass. Oxygen is produced as a by-product. The process can be summarized by the following equation;
[tex]6CO_2 + 6H_2O + light --> C_6H_1_2O_6 + 6O_2[/tex]
To explain the decrease in mass of the dark-grown plants, the loss of mass would be due to the breakdown of carbohydrates in the body of the plant through a process known as respiration. During this process, carbohydrate is broken down to release energy for the metabolism of the plant. Carbon dioxide and water are released as by-products and the entire process can be summarized by the equation below;
[tex]C_6H_1_2O_6 + 6O_2--> 6CO_2 + 6H_2O + ATP[/tex]
The inorganic source of new plant mass which is connected to the cellular process underlying the increase in mass is:
Carbon from carbon dioxideThe overall chemical reaction which is occurring in the plant cells and connected to the cellular process underlying the decrease in mass is:
Breakdown of carbohydratesAccording to the given question, we are asked to show how the group of plant cells which are used as part of an experiment actually increases in mass and how the decrease in mass of the dark grown plants comes about.
As a result of this, we can see that the inorganic source of new plant mass would be from carbon which is gotten from CO2 and feeds the plants with the help of chlorophyll with photosynthesis.
Furthermore, the decrease in mass of the dark grown plants would be as a result of the catalyst of the carbohydrates in the plant through respiration where carbon is the by product and energy is released.

True
Explanation:
When we have a narrow gene pool for our offspring that narrows down the favorable traits that the offspring can have. This can lead to the offspring having more traits that are not so good in its family tree and leave it not suited for a given environment. On the other hand, if the diversity is large it will lead to more offspring having more favorable traits and more adaptation to their environment.

Explanation:

Fruit flies when crossed produce the F1 generation with straight wings, and the F2 generation with straight and curly wings as the P generation had straight wings and curly wings. Thus, options B, C, and G are correct.
What is Mendel's cross?Mendel crossed plants to produce the F1 and F2 (filial) generations that involve the dominant and recessive alleles. The different phenotypic and genotypic ratios were predicted by the cross.
The crosses are attached to the image below.
The parent generation in fruit flies are purebred dominant and recessive = WW and ww
When they are crossed produces, F1 generation with offsprings with straight wings (Ww). Now the gametes of F1 are crossed to produce 16 offsprings with ratios as,
Phenotype ratio = 3 :1
Therefore, options B, C, and G are correct. Straight-winged flies will produce straight wings in F1 and both straight and curly wings in F2.
