Answer:

holozoic , saprophytic , parasitic

Answer:

Water, ions, glucose, fluids

Explanation:

This is because the nephron have network of cappilaries vessel called glomerulus . This glomerulus filter blood in the kidney to make urine. The hydrostatic force cause the filtrate to be filtered out through pressure.

The nephron also posses tubule which help to return needed or essential substances like protein, ions to the blood and then remove waste products from the blood.

Answer:

Explanation:

The troposhere is the lowest layer in the atmosphere and the largest in mass taken about 80% of the mass.

The higher the altitude in the troposphere the lower the atmospheric pressure. At the bottom of troposphere the air is very warm and it gets cool as one moves through the troposphere. The density of the air also decrease with altitude or height above the sea level and this cause the cabins of high-flying jet aircraft to be pressurized.

The atmospheric pressure in the troposphere is lower with higher the altitude (distance from the ground).

The troposphere is the lowest layer of the atmosphere of Earth. This layer contains the 75% of total mass of the atmosphere.

The variation in the temperature and atmospheric pressure in troposphere layer-

Thus, the atmospheric pressure in the troposphere is lower with higher the altitude (distance from the ground).

Answer:

Hardy-Weinberg equilibrium

Explanation:

The Hardy-Weinberg law is established in it is that in a sufficiently large population, in which the matings occur randomly and that is not subject to mutation, selection or migration, the gene and genotype frequencies remain constant from generation to generation, once a state of equilibrium has been reached that is reached after one generation at autosomal loci. A population is said to be in equilibrium when alleles from polymorphic systems maintain their frequency in the population through generations.

Answer: Eukaryota are organisms with nucleus within cells.

Explanation: Animals, Plants, Fungi, and Protists are all part of Eukaryota.

Answer:

The butterfly population would decrease or die out.

Explanation:

If the population of the green butterfly had depended on these "green plants" or leaves, they would die out without them since they use these green plants to camoflauge and blend in with them. Its something they can use to hide away from predators, and be safe from them.

Homeostasis is a regulating process of the body in response to external environments, digestive system provides glucose for cellular respiration.

Organ systems in our body are regulated with each other and these interactions maintain homeostasis.

The respiratory system interacts with the circulatory system for gaseous exchange and the excretory system depends on the circulatory system for blood filtration, and the nervous system regulates the system through the brain.

Homeostasis is necessary because the external environment can change anytime, and the digestive system maintains food conditions according to the body's needs.

Therefore digestive system maintains homeostasis by providing glucose for cellular respiration.

Answer:

(A) nitrates—proteins

Note: The question is not complete. The complete question is given below:

Which combination correctly pairs a product from a reaction in the nitrogen cycle with a molecule

synthesized by plants using that product?

(A) nitrates—proteins

(B) ammonia—carbohydrates

(C) nitrogenous wastes—nitrites

(D) atmospheric nitrogen—nitrates

(E) atmospheric nitrogen—ammonia

Explanation:

The nitrogen cycle refers to the cycle through which nitrogen is transferred for use through both living and non-living things, involving the atmosphere, soil, water, plants, animals and bacteria.

The nitrogen cycle is especially important for living things because nitrogen is essential for the formation of amino acids which form proteins.

The nitrogen cycle occurs in five stages:

1. Nitrogen fixation - Nitrogen gas from the air is converted to nitrate compounds by nitrogen-fixing bacteria in soil or root nodules. Lightning also converts nitrogen gas to nitrate compounds.

2. Nitrification - Ammonia is converted to nitrates by nitrifying bacteria in the soil.

3. Assimilation - Plants absorb nitrates from the soil and use them to make proteins. The plant is then eaten by an animal and are used to produce animal protein.

4. Ammonification- Decomposers break down the bodies of dead organisms, urine and faeces converting them to ammonia in the soil, which is then converted to nitrates by nitrifying bacteria.

5. Denitrification - Denitrifying bacteria in the soil break down nitrates and return nitrogen back to the air.

From the above stages and the options provided, the correct option is A - nitrates from the nitrogen cycle is converted to protein by plants.

Answer:

Cellulose - It is described as a complex carbohydrate that forms the main constituent of the cell wall in most plants and is important in the manufacture of numerous products like pharmaceuticals, textiles, etc.

Chlorophyll - Any of a group of green pigments that are found in the chloroplasts of plants and in other photosynthetic organisms such as cyanobacteria.

Chloroplast - An organelle found in the cells of green plants and in photosynthetic algae, where photosynthesis takes place.  

Bryophyte - Any plant of the division Bryophyta, defined "sensu lato" to comprise the mosses, liverworts, and hornworts, and corresponding to all embryophytes that are not vascular plants.

Pterophyte - It is characterized as any fern(seedless plant) that is a division of Pteridophyta.

Answer:

the dissolved oxygen of the water decreases.

the fish need the oxygen for respiration, breathing through their gills.

Explanation:

The salinity decreasing doesn't affect the pickerel, because it's a freshwater fish. no salt needed.

more light penetrating the water just means that more aquatic weed or grasses would grow, giving the pickerel more area to spawn their eggs.

temperature increase in the summer has no affect on the fish, since the spawning happens in late winter.
