How gamete formation leads to genetic variation.​

Biology
2 answers:
KIM [24]2 years ago

Answer:

Explanation:

During fertilisation, 1 gamete from each parent combines to form a zygote. Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.

Answer:

The process that produces gametes is called meiosis. During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. ... At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.

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.

Which process most likely enabled the formation of the early protists? A. photosynthesis B. endosymbiosis C. conjugation D. bina
natita [175]

Answer:

Answer B. Endosymbiosis

Explanation:

Early protists were first eukaryotic organisms and had several membrane bound organelles. The anaerobic protists evolved by acquiring purple bacteria. The purple bacteria have the ability to carry out aerobic cellular respiration. The endosymbiont transformed into mitochondria in due course of evolution. Similarly, the photosynthesizing protists were evolved by endosymbiosis of cyanobacteria which in turn was transformed into chloroplast during further evolution.

Some bacteria living in the ocean floor can turn methane (a gas) into food.
Nesterboy [21]

Answer:

Option A

Explanation:

Only an autotrophic species can convert methane into food.  

Deep below the sea, methane and hydrogen sulfide are found in abundance. These gases get mixed into the sea water.  

Autotrophic bacteria containing phosynthetic pigments oxidize these dissolved gases thereby producing food.  

Hence these autotrophic bacteria’s will be considered as producers as they produce food.  

Thus, option A is correct.
