Answer: Decrease

Explanation:

Pollinator loss could result in a high economic loss.

Answer:

by weathering and becoming new parent material

Explanation:

Soil formation occurs as a result of the the decay or the remains of plants and animals which are used up.

Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;

I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.

II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.

Hence, the type of bedrock under a soil affect the characteristics of the soil by weathering and becoming new parent material i.e the contribution of small rock particle to the soil.

Answer:

vertebrates have backbone and invertebrates don't have backbone

vertebrates eg; goat,fish,cow

invertebrates eg: jelly fish ,snail, earthworm

Answer:

Invertebrates are those that do not possess a vertebral column or backbone while Vertebrates are those where vertebral column or backbone is present.

Invertebrates are those that do not possess a vertebral column or backbone while Vertebrates are those where vertebral column or backbone is present.The main difference between vertebrates and invertebrates is that invertebrates, like insects and flatworms, do not have a backbone or a spinal column. Examples of vertebrates include humans, birds, and snakes.

Explanation:

Answer:

Domoic acid is a kainic acid-type neurotoxin that causes amnesic shellfish poisoning. It is produced by algae and accumulates in shellfish, sardines, and anchovies. When sea lions, otters, cetaceans, humans, and other predators eat contaminated animals, poisoning may result.

Explanation:

Blooms of algae affect ALL TROPHIC levels because domoic acid is a neurotoxin that accumulates in different species (e.g., shellfish, sardines, anchovies, etc) which are eaten by higher consumers (e.g., manatees and dolphins), thereby altering the equilibrium of the food chain.

A food chain refers to the transfer of matter and energy as food from different trophic levels in an ecosystem.

The food chain is sustained by organisms called producers (.e.g., algae in a marine ecosystem), which are found at the most basal level of the chain.

The primary consumers (e.g., marine invertebrates) are organisms localized at the second trophic level. These organisms (primary consumers) eat producers.

The secondary consumers are organisms found at the third trophic level, which eat primary consumers, and so successively to all major trophic groups.

Blooms of algae alter the whole food chain because domoic acid is a poison that accumulates in the body of the organisms at all trophic levels.

In consequence, marine consumers at higher trophic levels (e.g., manatees and dolphins) are also affected by blooms of algae.

In conclusion, blooms of algae affect ALL TROPHIC levels because domoic acid is a neurotoxin that accumulates in different species (e.g., shellfish, sardines, anchovies, etc) which are eaten by higher consumers (e.g., manatees and dolphins), thereby altering the equilibrium of the food chain.

Considering a well-trained 130-pound female marathon runner named Jordan.

The grams of glycogen Jordan is storing in her body is 884 grams.

Given that:

a.

The total mass of glycogen that Jordan is storing in the body of 130 pounds is:

b. The amount of Calories she has stored in the body of 130 pounds is calculated as follows.

Since 1 gram is equivalent to 7.716179 kcal

∴

c.

Fat is a class of food that the when consumed provides energy to the body. It is usually stored as fatty acid and is measured in pounds.

One pound of fat usually requires an energy of about 3500 calories to burn.

The weight of the glycogen in fat will be:

d.

The body stores most of its extra energy as fat rather than glycogen because the body after 8 hours of eating, body starvation starts to occur. At this stage, the stored fat is designated to supply energy to the body.

e.

Given that:

In order for her to be able to run at the same pace beyond the 24 miles, she needs to consume fatty food substances that can help her store additional fat that can be used to provide energy during the marathon race.

Therefore, we can conclude that we have understood the grams of glycogen that Jordan can store in her body, the conversion from grams to calories, and how Jordan can achieve the marathon of 26.2 miles.

Answer:

b. The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.

Explanation:

Transformation is a genetic process by which bacteria take up foreign genetic material from the surrounding environment. In consequence, this process does not involve direct cell-to-cell interaction. Transformation allows the occurrence of horizontal gene transfer (HGT) events among different bacteria capable of exchanging extrachromosomal DNA plasmids, thus increasing genetic diversity in bacteria. Many different types of bacteria can acquire foreign genes, including antibiotic resistance genes, by HGT events involving plasmids, transposable elements, bacteriophages, etc.

Answer:

The correct answer is - option D. nonsense and frameshift.

Explanation:

If there is a change in the sequence of DNA resulting in premature stop codon mRNA during transcription is known as a nonsense mutation and result in a non-functional protein.

a frame-shift mutation takes place when at least two nucleotides are altered and there are less chances to be changed by two others coding for the same nucleotide. It leads to a non-functional protein.

Answer:

The correct answer is - option B. mitochondria have their own nucleus.

Explanation:

Endosymbiotic theory is a evolutionary theory which explains how eukaryotic cells evolved from prokaryotic organisms.

Evidences of endosymbiotic theory are:

1. Mitochondria and chloroplasts are double membrane bound cell organelles. The inner membrane probably evolved from the plasma membrane of engulfed bacterium and outer membrane from the plasma membrane or endoplasmic reticulum of the host cell.

2. Almost similar size of mitochondria and chloroplast and bacteria and their ribosomes.

3. Cristae of mitochondria resemble the folded membranes is groups of bacteria.

4. Mitochondrion and chloroplast both have circular DNA similar to those of bacterial DNA.
