B. DNA

Explanation:

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA. The information in DNA is stored as a code made up of four chemical bases: adenine, guanine, cytosine, and thymine.

Trait approaches to leadership propose that leadership ability arises from distinctive personal characteristics. These personality traits shape personality.

Personality refers to the singular and unique patterns of thoughts, emotions and behaviors that exhibit a person.

The trait approaches represent different methodologies to analyze the personality of a person (for example, his/her leadership skills).

Answer:

1. Today instead of rotating upright, The earth's axis is tilted 23.5 degrees. The angle varies a little over time, but the gravitational pull of the moon prevents it from shifting by more than a degree so. This tilt is what gives us seasons.

2.The cooling effects of more indirect sunlight cause autumn and winter. Because of the earth's approximately 23.5° tilt, the season in the northern and southern hemispheres reversed, about six months apart from each other.

Answer:

None of them are correct because omnivores, from the root word "Omni" meaning "all", means omnivores eat both plants and animals. Then, herbivores only eat herbs, meaning plants, so both of them are wrong. Animals that eat other animals but not plants are called carnivores.

Fixation or volatilization, mineralization, nitrification, immobilization, and denitrification.

The sequence is as follow: Fixation, Nitrification, Assimilation, Ammonification and Dentrification.

The nitrogen cycle is the process by which nitrogen is converted into different chemical forms and moves between the biosphere, atmosphere, and geosphere. The stages of the nitrogen cycle, in order, are:

Nitrogen fixation: Nitrogen gas in the atmosphere is converted into a usable form, such as ammonia or nitrite, by nitrogen-fixing bacteria.

Nitrification: Ammonia or nitrite is converted into nitrate by nitrifying bacteria.

Assimilation: Nitrate is taken up by plants and converted into organic nitrogen compounds, such as proteins and nucleic acids, through the process of assimilation.

Ammonification: Organic nitrogen compounds are broken down by decomposers, such as bacteria and fungi, into ammonia or amino acids.

Denitrification: Ammonia or nitrite is converted back into nitrogen gas by denitrifying bacteria, completing the cycle.

Answer:

A.TRANSPIRATION

Explanation:

Trees have deeper roots than other plants, which implies they can access and pump up larger soil water volumes for transport to the leaves for transpiration and growth. ... The energy needed to evaporate all that water is withdrawn from the environment and leaves the system as embedded latent heat.

Which means if the forest got messed up the transpiration would be jacked up

Answer:

Explanation:

Answer is A

Mitochondria are the "powerhouses" of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They're responsible for capturing light energy to make sugars in photosynthesis.

Answer   Migration, in turn, covers both immigration and emigration. Another key difference is, immigration is permanent while migration doesn’t have to be. People who travel and stay in a country for a few months — for instance, because of a seasonal job they have — are also called migrants.

Option (B) low to high is right Answer

We know that, Active transport moves ions and molecules across a membrane against the concentration gradient. It requires energy.

The characteristic features of active transport are:

-The movement of molecules in case of active transport is from lower concentration to higher concentration so it shows uphill transport.

-These have carrier proteins that are highly specific like enzymes for the substances to be carried across the membrane.

-The process of active transport can be inhibited by inhibitors that react with the protein side chains.

-The transport rate reaches its maximum when all the protein carriers are in use or get saturated with the substances to be carried.

The various types of processes that depend on active transport are:

-Absorption of amino acids from the gut.

-Absorption of mineral ions by plant roots.

-Excretion of urea and hydrogen ions by the mammalian kidney.

-Exchange of sodium and potassium ions in nerve cells.

-Filling of the contractile vacuole in amoeba.

The phloem in the leaves of a plant is rich in sugars because of the high rate of active transport.

Answer:

pollen and seeds

The adaptation do ferns, gymnosperms, and angiosperms have that mosses do not have they have seeds and pollen for reproduction.

Mosses make up the majority of bryophytic plants. They are small plants with a simple structure, they do not have conducting vessels, flowers and seeds.

Ferns have a vascular system that transports food, water and minerals to the upper parts through hair-like roots. Mosses do not have true roots or a vascular system. Instead, they absorb water and minerals from the soil where they grow.
