A gene contains the base sequence GTA TAG. Give one example of a silent point mutation on this gene. Explain why it would be silent.
Answer:
GTC. It would be silent because it does not have an effect on the amino acid sequence.
Explanation:
GTC is the mutation. It does not change anything to the extent of affecting the amino acid sequence, therefore it is silent. It is best to write the answer exactly as written in the "answer section", to avoid mix-up or confusion.

Which of the following processes that occur by chance result in a loss of genetic diversity? (Choose all that apply)
A) inbreeding
B) genetic bottleneck
C) founder effect
D) outbreeding
Answer:
inbreeding
genetic bottleneck
founder effect
Explanation:
These different types of genetic drift change the allelic frequencies in a population through chance.
Inbreeding, genetic drift, restricted gene flow, and small population size all contribute to a reduction in genetic diversity. Fragmented and threatened populations are typically exposed to these conditions, which is likely to increase their risk of extinction
Answer:
inbreeding
genetic bottleneck
founder effect
Explanation:

When a bee visits a flower for a meal of nectar, which part of the flower deposits pollen on the bee's fuzzy body?
A. stamen
B. sepal
C. petals
Answer:
Option A
Explanation:
Your answer is option A or the "stamen." The stamen is a reproductive organ of a flower that produces the pollen. When a bee visits for a meal of nectar the stamen is the part of the flower that deposits pollen on the bee's body. It's not option B because the sepal functions as protection for the flower, and it's not option C because the petals main purpose is to attract the bees to the flower to pollinate.
Hope this helps.
3.Nonvascular plants have flagellated sperm that must swim to find the eggs. Why is this a limitation for land plants
Flagellated sperms with capacities to swim in order to find eggs will not work with land plants because swimming requires water.
Fertilization in plantsAquatic plants usually produce flagellated male gametes or sperms that are capable of swimming to find the female gametes or eggs. The female gametes are usually non-motile, unlike the male gametes.
The swimming is made possible by the water in aquatic environments.
In land plants, however, this is not possible because of a lack of water. most land plants have male gametes in the form of pollen. Pollens are either carried by the wind or insects to meet the female gamete for fertilization - a process known as pollination.

Describe how hibernation has helped bear species survive.
HELP ME ASAP PLEASEEE!!!!!
Answer:
During hibernation, the animal's body temperature, heart rate and breathing rate all drop to significantly lower levels. Animals do this to survive the winter because the weather is cold and food is scarce.

Petroleum is a fossil fuel, and an example of
a nonrenewable resource. Gasoline powered
cars run off of petroleum products.
However, there are energy efficient
technologies such as the hybrid car shown in
the picture that reduce the use of fossil fuels.
Why do you think hybrid cars are an
example of energy-efficient vehicles? Can
you think of any other modes of
transportation that increase energy
efficiency?
Answer: The reason the hybrid car is better for this is that it is electrically powered to run or at least some of them. therefore thanks to this people can drive without affecting the ecosystem like with petroleum or fossil fuels.
