If white wool (W) is dominant over black wool (w), can two sheep with black wool produce an offspring with white wool? Explain your answer.
Answer:
No, the offspring of two black sheep cannot have white wool. Since the black wool allele is recessive, both parents have to be recessive (ww) and so do not carry the dominant white wool allele. The only allele the parents can pass to their offspring is the black allele.

Which scenario describes an interaction between two of Earth’s spheres?
Water flows from a stream to a lake.
Gravity moves rocks to another location.
Lions use energy to catch other animals for food.
Bears dig big holes in the ground to protect their young.
Answer:
The scenario that describes an interaction between two of Earth's spheres is "bears dig big holes in the ground to protect their young".
Explanation:
The Earth spheres include the biosphere, the hydrosphere, the geosphere, and the atmosphere. In this context, there is an interaction between two spheres: the biosphere and the geosphere, when a bear digs holes in the ground because a living organism that is part of the biosphere is modifying the structure and shape of superficial soil, which is part of the geosphere.

How does natural selection change the frequency of genes or traits over many generations? Biology students conducted an experiment mimicking genetic variation and coloration. Students used different colored beans to represent animals that might be prey: mice, for example. A student in each group was the predator: a hawk. Beans (mice) were randomly scattered on multicolored floor tiles, each color within four tiles. The hawk collected mice (beans) for 10 seconds. Mice not eaten reproduced. Three generations of data a shown in the table.
Genetic variation helps to drive natural selection and potentially, evolution. Red, white, and striped beans (mice) represent offspring that are the product of meiosis and sexual reproduction. Black and speckled beans (mice) are the result of mutations. Using the student data analyze the effects of these mutations on natural selection.
A) The color mutations provided a survival advantage to these two populations of mice.
B) The advantage of the mutations is dependent on the environment and external conditions.
C) While mutations provide genetic variation they did not play a role in natural selection.
D) The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.
Answer:
D) The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.
The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.
Natural selection refers to the observation that organisms that are more suited and adapted to their environment live long enough to survive and reproduce thereby passing on their favorable characteristics to their offspring.
The mutation in which the mice became speckled was shown to be an advantage from the table. Hence, the speckled mutation provided an advantage while the black mutation was a disadvantage for survival.

Which of these forms when air moves in the directions shown by the arrows
in the diagram?
A ) Valley Breeze
B) Land Breeze
C ) Mountain Breeze
D ) Sea Breeze
Answer:
C.
Explanation:
Please do brainless :)
Mountain breeze refers to the fact that the surface breezes are coming from the mountain and blowing into the lowlands. Thus, option C is correct.
What is the movement of air in mountain breeze?The air cools during the night and flows into the valley from the mountainside.
As a result, the breeze blows in the other direction; it travels from the mountains to the plains and valley floor. This wind is therefore referred to as the mountain breeze.
As the air rushes in to fill the space, the air pressure decreases and a gust of wind is produced. A valley breeze, on the other hand, develops when cooler air in the valley falls to fill the space left by the warm air rising.
Therefore, Mountain Breeze in which air move from high pressure to low pressure.

Which renewable resource is not safe for the environment and why?
Answer: Biomass
Biomass produces gas or many sorts of waste products which are mostly used in burning and cooking. It is plant or animal material used as fuel to produce electricity or heat. Examples are wood, energy crops, and waste from forests, yards, or farms.
But the reason why it can be harmful is because biomass can produce gases like methane. Methane is a greenhouse gas which can harm the environment and reduce the ozone layer that stops harmful UV light from reaching the earth atmosphere.

vermiform appendix is a vestigial organ in human being give reason.
Answer:
The human appendix may be considered as a vestigial organ as it has been proved that the removal of the organ after infancy does not create any harm. Vestigial in that sense means that the vermiform appendix seemingly has no functions or is useless now but they might have had functions previously which are lost someway due to evolution.
Explanation:
Vestigial organs are organs, tissues or cells in a body which are not functional anymore the way they were in their ancestral form of the trait. It is therefore authentication of evolution and hence were helpful in explaining adaptation.
