What would be an individual with a genotype of XY would be ?
A. not possible
B. a male
C. a dwarf
D. a female
Studies have shown that children are especially vulnerable to the effects of ultraviolet (UV) radiation. Tanning beds expose the skin to nearly ten times as much UV radiation as natural sunlight. With that knowledge, a law was passed in some states to prevent individuals under the age of 18 from using tanning beds. Which statement best explains why UV radiation is so harmful?
a) It can increase harmful DNA mutations in cells.
b) Diseases are all caused by exposure to environmental factors.
c) Homeostasis in an organism is increased by the presence of UV radiation.
d)UV Radiation decreases the likelihood that mutations will occur.
Hello there!!
The answer, I think, would be A.
UV radiation can create problems in the correctness of cell replication, which can result in mutated cells.
I hope this answers your question!
Tanning beds can increase harmful DNA mutations in cells. So, the correct option is A.
What are Tanning beds?In order to tan individuals, a tanning bed emits UV radiation (make their skin darker). If someone spends too much time in the tanning bed, it can also burn their skin, much like the sun. Many types of tanning beds exist. Using tanning beds can lead to more damaging DNA alterations in cells.
Special fluorescent lights (16–32 per tanning bed) that produce both visible and UV light are used in tanning beds. They employ a ballast system, like all fluorescent lights, to keep the amount of electricity going to each lamp to a maximum of 100 watts per lamp. A specific acrylic, or clear shield, is used over the bulbs in tanning beds.
Therefore, the correct option is A.

Pollination occurs when pollen lands on the -
A. style
B. anther
C. stigma
D. filament
E. ovary
Answer:
C. stigma
Explanation:
"stigma"
Fertilization in flowering plants happens through a process called pollination. Pollination occurs when pollen grains from the anther land on a stigma. After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary.

explain the differences between the particles of a pure substance and the particles of a mechanical mixture
Answer:
A substance is pure if it is a single substance, and it is made up of only one type of particle. If there is more than one substance, and therefore more than one type of particle, it is a mechanical mixture, the particles can be easily distinguished, due to their non-uniform composition. The composition of a mechanical mixture is variable and their components may be separated by physical or mechanical means because they are not chemically bound.
Explanation:
A pure substance is one that has a composition and characteristic properties that do not change, whatever the physical conditions in which it is found; that is, the physical transformations do not affect it. In other words, pure substances will be made up of particles that are identical to each other. Mechanical mixture are the result of the physical union of two or more substances which are called components, these can be elements or compounds, whose particles do not mix uniformly. The components of the mixtures have different properties, such as the state of aggregation, the density or the solubility. These properties allow substances to be identified and facilitate the separation of the components of a mixture, that is, through physical or mechanical processes we can isolate and obtain the components that make up the mechanical mixtures.
When resistant bacteria multiply, what do they pass on to the next generation?
Answer:
Antibiotic use promotes development of antibiotic-resistant bacteria. Every time a person takes antibiotics, sensitive bacteria are killed, but resistant germs may be left to grow and multiply. Repeated and improper uses of antibiotics are primary causes of the increase in drug-resistant bacteria.
The resistant bacteria can reproduce rapidly because their competition (the non-resistant bacteria) has been destroyed by the antibiotic. When the resistant bacteria reproduce, they produce genetically-identical copies. These copies will all be resistant to the antibiotics.

Archean
Hadean
Mesozoic
Proterozoic
Answer:
Proterozoic
Explanation:
Stromatolites appear on Earth in the end of Proterozoic era because Proterozoic extended from 2500 million years to 542 million years. The stromatolites were present on earth about 542 million years ago. The stromatolites present in large number on the sea shores around the world and are considered as the Earth's first visible life form which can be seen through naked eye. These stromatolites were the first known organisms in which photosynthesis occurs and produce free oxygen..

Compare and contrast genetic engineering to the process of natural selection. Select all statements that are true
Available options are:
1. By selecting the genetic information that is passed on to future generations, genetic engineering is similar to natural selection.
2. Unlike natural selection, genetic engineering selects the organisms most beneficial to the environment.
3. By selecting the genetic information that is passed on to future generations, genetic engineering can happen at a different rate than natural selection.
4. Like natural selection, genetic engineering may be used on all organisms, including humans.
5. The effects of genetic engineering apply only to the organism selected, but natural selection affects the entire population.
Answer:
1, 2, and 3
Explanation:
Given that Genetic engineering is a scientific process of altering the genetic makeup or elements of organisms such that these organisms develop preferable traits.
On the other hand, Natural selection is a process that deals with the impartial selection of traits, that is without human input, thereby making organisms more fitted to their immediate environment.
Therefore, considering the available options, the comparison, and contrast of genetic engineering to the process of natural selection are:
1. By selecting the genetic information that is passed on to future generations, genetic engineering is similar to natural selection.
2. By selecting the genetic information that is passed on to future generations, genetic engineering can happen at a different rate than natural selection.
3. Like natural selection, genetic engineering may be used on all organisms, including humans.

What explains two green pea pod plants producing 25% plants with yellow
pea pods? (green is dominant, yellow is recessive)
Answer:
two heterozygous pairs
Explanation:
the genotype products of Gy and Gy would be GG, Gy, Gy, and yy, making a 25% chance for yellow
The heterozygous pairs are those that have different alleles in the two chromosomes a and a re a set of the dipole individual.
The 2 green pea pod plants produce 25% of the yellow sea pods where the green is the dominate and yellow is recessive. As the chromosome is inherited in both the parent the gene is same. Thus the dominant green color and yellow pod plants will have a mix of genes.Learn more about the green pea pod plants producing 25% plants.

Explain why the BREATHING RATE of students increased after exercise. Include information about what happens at the level of body systems and at the cell.
Explain why the HEART RATE of the students increased after exercise. Include information about what happens at the level of body systems and at the cell.
Answer:
When exercising, your body uses more oxygen and produces more carbon dioxide and your muscles also need energy to contract because of this your breathing needs to increase.
Hope this helps :D
Answer:
for why the heart rate increase is because during exercise alot energy is used which means alot of oxygen also used for respiration ,the cells need oxygen to meet the demand of energy so breathing rate increase then to transport oxygen faster then the heart rate also increases.
