rough hard, 12 smooth soft
Identify which traits are dominant, and either support or refute the hypothesis
that the traits rough/smooth and soft/hard assort independently according to
Mendel's law,

Answers

Answer:

rough (RR or Rr) and hard (HH or Hh), are the dominant traits. smooth (rr) and soft (hh), are the recessive traits

We reject the hypothesis because genes are linked, so they do not assort independently.

Which of the following is a source of energy made from plant and animal remains?

Answers

Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals.

In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.

These are sometimes known instead as mineral fuels.

The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat.

Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.

The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.

A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.

Answer:

Darwin's theory of evolution state that"all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce".

functional group of Acetaldehyde​

Answers

Answer:

―CHO

Explanation:

Organic compounds are compounds that contain carbon-hydrogen bonding in their structural formula, hence, virtually all organic compounds are referred to as HYDROCARBONS. Organic compounds consists of a wide variety of groups, which are individually identified by their FUNCTIONAL GROUP.

The functional group of an organic compound is responsible for its chemical behavior irrespective of other atoms in its structure. According to this question, ALDEHYDE GROUP is an organic compound also called ALKANAL. It has the functional group as follows:

R - C - H - O

Where R is a side chain

- The second member of the aldehyde group is called ACETALDEHYDE with the chemical formula; CH3CHO. Since it is a member of the aldehyde group, its functional group is -CHO.

Explanation:

It depends if the genotypes are hetero.zygous or resessive/dominant homo.zygous. Being colorblind could be represented by a resessive genotype like, bb. if their son/daughter has Bb or bb or their son/daughter in law has a resessive trait then having a color blind grandchild maybe possible. The colorblind grandson has parents that both have at least 1 resessive trait, then the grandson could not be colorblind.

The first unstable compound formed during C3 cycle is:
(a) 3-carboxy,2-keto, 1,6 bi phosphorobitol
(c) 2-carboxy,3-keto,1,5 biphosphorobitol
(b) 2-carboxy,3-keto,1,5-biphosphorobitol
(d) 3-carboxy,3-keto, 1,6-biphosphorobitol​

Answers

Answer:

(b) 2-carboxy,3-keto,1,5-biphosphorobitol

Explanation:

2-carboxy, 3-keto, 1,5-biphosphorobitol is the first unstable molecule formed during the C3 cycle. Due to its instability, this molecule is quickly broken down into two molecules each containing 3 carbon atoms, called 3-phosphoglyceric acid, this breakdown is done through water in a process known as hydrolysis.

high levels of nitrates
high levels of phosphates
zero turbidity
all of the above

Answers

Answer:

all of above

Explanation:

all of the above

Answer:

Zero Turbidity

Explanation:

High phostphate levels cause excessive algea growth and a decreased level of dissolved oxygen. High levels of nitrates are caused by animal or human waste and the overuse of chemical fertilizers. Low turbidity causes the water to be more clear so zero turbidity is the only right answer. I got it right on my test too

1. Identify one population of organisms shown in the food web, other than rabbits or mice, that would likely be affected by the introduction of snowy owls AND explain why their population would be affected.

2. State which level, a, B, or C, contains the least total available energy. Support your answer.

Answers

Answer:

The population if snakes will decline because there will be competition between snakes and snow owls. The snow owls will eat the mice, but if there's only a small population of mice. Only a few snakes will eat, other snakes will die of starvation. There will be competition between snow owls, hawks and mountain lions, but they have other sources of food, unlike snakes.

Level C contains the least amount of energy. This is because each level gets less and less energy per meal, beacuse energy is released by each organism.
