2. In sheep black wool is recessive to white wool. What happens when you mate a black ram (male) to a heterozygous ewe (female). W= white, w = black.
Answers
Answer:
50% will be white (Ww) and 50% will be black (ww)
Explanation:
Here's what the punnett square should look like.
In order for the black ram to have its coloring it would need to have 2 recessive genes (ww). The female is heterozygous, meaning she carries both genes (Ww) but only exhibits the dominant gene, in this case white fur (though they can pass the recessive gene on to their children). Simply filling out the punnett squares shows the outcome of the offspring.

Solve the 3 following questions (btw this isn’t biology, my questions are Earth Science)
Answers
"Many processes work together to keep Earth's water moving in a cycle. There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration. These occur simultaneously and, except for precipitation, continuously."
"The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration."
"The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. Also, the cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth."
which change would lead to higher carbon dioxide levels in the atmosphere
A. An increase in photosynthesis
B. An decrease in animal
C. An increase in the burning of fossil fuels
D. An decrease in the destruction of forests
Answers
An increase in the levels of fossil fuels results in higher carbon dioxide levels in the atmosphere. So the correct option is C.
What are fossil fuels?The components of fossil fuels are decaying plants and animals. These fuels may be burnt to provide energy and can be found in the crust of the Earth. An example of fossil fuel is coal, as well as oil and natural gas.
Coal is a substance that is typically found in sedimentary rock formations, which are collections of rock, dead plant and animal materials, and layers of silt. A chunk of coal must contain more than 50% fossilized plant material.
Shale is one sedimentary rock type that contains oil in its native form. The thick oil that may be used to generate gasoline is created by heating this substance. Typically, pockets of natural gas can be found atop oil deposits. Additionally, sedimentary rock strata devoid of oil might contain it. Methane is the main component of natural gas.
Therefore, an increase in the burning of fossil fuels will result in higher carbon dioxide levels in the atmosphere. So the correct option is C.

A woman heterozygous for polydactyly (extra fingers and toes), a dominant trait, is married to a normal man. What is the probability of producing an offspring that has extra fingers or toes?
Answers
Answer:
The correct answer is -50%
Explanation:
Polydactyly is a dominant trait where a person gets an extra finger or toes the dominant allele is represented by P = allele for polydactyly, and the recessive allele represented by p = normal allele
So, the heterozygous woman will be - Pp & the normal man will be - pp. The presence of one allele of polydactyly will be able to show its effect as it is dominant.
Cross between heterozygous woman & normal man:
Gametes:
P p
p Pp (Show polydactyly) pp (Normal phenotype)
p Pp (Show polydactyly) pp (Normal phenotype)
From the above Punnett square, the probability of an offspring that has extra fingers or toes will be 1/2 or 50%.
Polydactyly is a condition that occurs wherein individuals have more than the normal amount of fingers and toes. It is also a genetic condition and as well heritable.
The probability of producing an offspring with extra toes or fingers in a cross between an heterozygous and a normal is 50%.
Let P represent the dominant and p the recessive
Pp (heterozygous) and pp (normal)
(woman) P p
(man) p Pp pp
p Pp pp
50% 50%
Therefore, the probability of producing an offspring with extra toes or fingers (Pp) is 50%.

Consuming nitrogen is not a cell process. The given statement is false.
What impact on plants due to depletion of nitrates or nitrogen?Nitrate plays a very important role in the ecosystem and due to presence of nitrogen plants grow fastly and produce large size of fruits and flowers.
Nitrate has a common inorganic ion found in the plants that has to be required for the proper growth and development of the plant.Many growers including nitrates in their nutrient regiment just to stimulate plant growth. Plants has acquired much nitrate through root intake from the soil and water present around them.
Hence due to the depletion of nitrogen, plants are getting turning to yellow and this shows that it produces smaller fruit. In modern era farmers has been adding nitrogen containing fertilizers which produce large amount of grains, foods and fruits which is also free from diseases.
