The data suggests that there is no change in height of sheep because of

Hardy Weinberg equillibrium.

Explanation:

Data given:

heights of 200 sheeps remains the same for two years.

reason=?

There is no change in the phenotype of the sheep population during two years as there is no effect of environmental factors, no evolution or genetic drift in the population. Such population happens due to Hardy Weinberg equillibrium.

This principle says that there will be no genetic variation in a population when no evolution causing factors are there. These factors are environmental, mutation, genetic drift, natural selection or gene flow.  When no new alleles are added in the population it remains same.

Thus in case of the 200 sheeps it is assumed that they were in Hardy Weinberg equillibrium.

Answer:

The process of natural selection acts on height only in male sheep. this scenario may be cause by sexual selection . females are choosing taller mates for reproduction , leading to an increased likelihood that their offspring will inherit these genes.

Answer:

Codeine

Explanation:

Codeine is an opiate and is used to treat mild and moderate pain. It is also the main ingredient in prescription based cough suppressant. It belongs to a class of drugs known as opioid analgesics.

Codeine is a naturally occurring phenanthrene alkaloid with opioid agonist and can be extracted directly from the plant although most codeine is synthesized from the opium poppy.

Which statements accurately describe the roles of decomposers in the carbon cycle?
ollegr [7]

Answer:

The question is incomplete, here's the complete question;

Which statements accurately describe the roles of decomposers in the carbon cycle? Check all that apply.

-Decomposers release carbon dioxide into the air as waste.

-Decomposers remove carbon dioxide from the air during photosynthesis.

-Decomposers break down the remains of dead plants and animals.

-Decomposers return carbon compounds to the soil.

-Decomposers use carbon to make food molecules.

The correct answer is;

Decomposers release carbon dioxide into the air as waste.

Decomposers break down the remains of dead plants and animals.

Decomposers return carbon compounds to the soil.

Explanation:

In the earth, all living things are made up of carbon. Carbon cycle is the process in which carbon travels from the atmosphere into living things in the earth and then returned into the atmosphere.  Carbon is released into the atmosphere through processes like respiration, decomposition, combustion etc. The carbon cycle explains how carbon is stored, made available to living things and replaced on earth. Plants absorb carbon in the form of carbon dioxide from the atmosphere and use it to produce food (glucose) and release oxygen in a process called photosynthesis. When animals feed on these plants , the carbon is transferred to them and thus passes it along the food chain. During respiration, animals release carbon dioxide back into the atmosphere. When the organisms eventually die, the carbon from them is put back into the atmosphere by decomposers so that other living organisms can use it. Decomposers break down dead organisms , releases carbon dioxide through cellular respiration and enriches the soil with nutrients.  The examples of decomposers are bacteria, fungi and worms. Bacteria decomposes most types of organic matter. Fungi are the main decomposers in the forest as they break down wood and the cellulose in plant cell walls. Decomposers are very important because they release carbon locked up in the dead organisms back into the atmosphere and without carbon dioxide in the atmosphere plants can not produce glucose and oxygen.

Anastaziya [24]

Answer:

The correct answer is included in the Explanation section

Explanation:

An organism with considerable more chromosomes than humans: the plant <em>Ophioglossum reticulatum</em> with 1260 chromosomes.

An organism with considerable fewer chromosomes than humans: the ant <em>Myrmecia pilosula</em> with 1 chromosome.

It might be thought that the chromosome number of a species is directly related to its complexity, meaning that an organism with a large number of chromosomes is more complex than an organism with a small number. However, this is not true. Chromosomes are structures of coiled DNA, and its number indicate how the cells wrapp their genomic material when they reproduce. The number of chromosomes is not related to the organism complexity, but rather the number of genes and their function.

Viral Spikies
kati45 [8]

Answer:

B)attach specifically to host cell receptors

Explanation:

Viral spikes are one of the envelope proteins. These proteins are coded for by viral genes. Viral spikes project from the envelope surface. They are also called peplomers. One of the functions of these spikes is to specifically interact with the receptors present on the surface of the host cell to mediate the attachment of the virus to the host cell surface. Viral spikes and the host cell surface receptors are complementary to allow their specific binding. For example, the spike protein of the SARS-coronavirus bind specifically to the human host cell receptor ACE2.
