Cardinals produce an average of six eggs in each clutch. If there are more than six, the parents cannot adequately feed the young. If there are fewer than six, predators may destroy the entire clutch. This is an example of

Answers

Answer 1

Answer:

Stabilizing selection

Explanation:

Stabilizing selection is a type of natural selection which favours the intermediate genotype and eliminates extreme genotypes (inferior and superior)
Cardinals produce an average of six eggs in each clutch,here production of six eggs represents intermediate genotype
Production of more than six eggs represents superior phenotype,this is not favored because parents in this case cannot adequately feed the young
If there are fewer than six eggs then this represents inferior phenotype,where predators may destroy the entire clutch

Based on this data, predict what will happen to the water in the Ogallala aquifer over the next decade.
Why is carbon so abundant in living things when oxygen is the most abundant element on Earth? Carbon atoms can bond with one another to make chains and cyclic structures whereas oxygen atoms cannot form chains or cyclic structures. Carbon atoms are found in compounds that are solids at room temperature whereas oxygen atoms are found in compounds that form gases Carbon atoms have lower mass than oxygen atoms, which keeps the masses of living things within desirable limits. Carbon atoms are more stable than oxygen atoms, which allows living things to have more stable compositions.

What is Mesosaurus fossil ?

The Mesosaurus fossils are the extinct species of animal which include freshwater reptilian predator with similar characteristics to the modern-day crocodilians.

Thes fossils are the ancient animal among the first two were used to support the theory of continental drift, the fossils of Mesosaurus are found in central, south of western, and southwestern South America regions on one side, and south of central, and western half of southern Africa.

Answer:

Mesosaurus, (genus Mesosaurus), early aquatic relative of reptiles, found as fossils from the Early Permian Period (299 million to 271 million years ago) in South Africa and South America. Mesosaurus lived in freshwater lakes and ponds. Elongated and slim, it measured about 1 metre (3.3 feet) long.

Explanation:

Mesosaurus fossils are found today in rocks in southern Africa and eastern South America. Back in the Permian those two locations were jammed against each other as part of the southern half of Pangaea called Gondwana, so the living range of Mesosaurus did not span an entire ocean.

What are the three responses from a vaccine?

Answers

primary response:

Programs the immune system to remember a particular disease agent by allowing it to "practice" on a weakened or killed version of the pathogen

Body may have a fever during this process

secondary response:

If a pathogen invades the body following a vaccine, the immune system can respond in a faster and greater magnitude than the primary response, which results in the creation of more antibodies to fight the pathogen and more memory cells to fight it in the future

Energy in most ecosystems must flow through autotrophs because ______.a. only autotrophs can convert solar energy into chemical energy
b. autotrophs are simpler organisms than heterotrophs
c. heterotrophs only generate a small fraction of their energy from photosynthesis.
d. all of the above

Answers

Answer: Option A

Explanation:

Only autotrophs have the ability to convert solar energy into chemical energy by the process known as photosynthesis. The autotrophs can trap all the radiant energy and only 10% of total energy that autotrophs have is transferred to another tropic level.

The energy from the producers are transferred to the herbivores and 10% of the total energy the herbivores have is transferred to another levels.

So, the energy flow takes place through the autotrophs because only they have the ability to perform photosynthesis.

The right answer for the question that is being asked and shown above is that: "d. all of the above." Energy in most ecosystems must flow through autotrophs because heterotrophs only generate a small fraction of their energy from photosynthesis; only autotrophs can convert solar energy into chemical energy; autotrophs are simpler organisms than heterotrophs

Kevin has his mother’s blue eyes and her shyness, which can both be attributed to __________.a. habits
b. heredity
c. environment
d. culture

Answers

the answer is B. Heredity

The correct answer would be heredity. As Kevin was getting his genes - Blue eyes are usually less likely to brown eyes in the equation. Anyway, if Kevin's mother had a very strong gene for the blue eyes dna strand , then Kevin would get the blue eyes. As Kevin was growing up, he most likely tried to be like a familiar figure. Which in this situation is his mother.

Removal of phloem tissue leads to gradual death of the plant. Why does this happen?Distribution of carbohydrates from the leaves to the other parts of the plant is affected.

Distribution of water and nutrients from the roots to the other parts of the plants is affected.

Distribution of water and nutrients to the flowers affects seed formation

Answers

Distribution of carbohydrates from the leaves to the other parts of the plant is affected.

The main function of the Xylem is to transport water and minerals throughout all parts of the plant. Phloem on the other hand is responsible for transporting organic molecules that are larger in size. The vascular system, consisting on the Xylem and the Phloem runs from the roots of the plats through the branches and upto the leaves. It controls the total transportation of the water and nutrients.
