How gamete formation leads to genetic variation.​

Answers

Answer 1

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.

Answer 2

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.

The adaptive features of Earthworm include streamlined body with no antennae or arms. The body of this organism is divided into segments.

What are the adaptive features?

Adaptation can be defined as a state of the physical or the behavioral characteristics of an organism which helps them to survive better in the surrounding environment. Adaptation is essential for the survival of  organisms in the new environment. These adaptations help the characteristics to become a part of the genetic makeup of the organisms.

An earthworm is a streamlined body organism with no antennae or fins or any arms or legs. The streamlined shape of the body is an adaptation to living in the narrow burrows which are present underground and the need to move easily through the soil. An earthworm has circular muscles which surround each body segment in the organism.

d. around Antarctica in the summer

Answers

Answer:

Option B, in the middle of the current gyres

Explanation:

The zones of upwelling have high productivity as they have adequate climate and weather condition along with availability of nutrients. The same is applicable for Equator and coastal regions. The productivity of Antarctica is low but not less than that of  current gyres as in the middle of the current gyres there are high current streams that reduces the biological productivity.

D.oceanic plates slide beneath continental plates.

E.overlying, adjacent plates are pulled apart.

Answers

Overlying, adjacent plates are pulled apart when magma convection currents flow away from one another.

What is magma conventions?

Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.

As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.Hence, option E is correct.

how does Sexual reproduction leads to genetic variation.​

Answers

Answer:

Sexual reproduction provides genetic diversity because the sperm and egg that are produced contain different combinations of genes than the parent organisms. ... Sexual reproduction involves meiosis, which is the process of a cell doubling its DNA, shuffling its genes, and then dividing the shuffled DNA among four cells.

Sexual reproduction leads to genetic variation due to:

• random fusion of gametes
• random assortment of chromosomes
• Gametes of each parent are a result of meiosis meaning gametes are genetically different so when they fuse together they form a new combination of genes in the zygote

Red blood cells, most white blood cells, and platelets are produced in the bone marrow, the soft fatty tissue inside bone cavities. Two types of white blood cells, T and B cells (lymphocytes), are also produced in the lymph nodes and spleen, and T cells are produced and mature in the thymus gland.

why do prevailing winds and positions of islands cause warm ocean currents to pass Christchurch in normal years

Answers

Prevailing winds and positions of islands cause warm ocean currents to pass Christchurch in normal years for the following reasons:

The prevailing winds in the region are generally from the southwest.The position of islands such as New Caledonia and Norfolk Island can also influence the movement of warm ocean currents in the region.

In the case of Christchurch, there are a few reasons why warm ocean currents tend to pass by the region in normal years:

Warm ocean currents are typically driven by prevailing winds, oceanic currents, and other factors such as the shape of coastlines and the positions of islands.

The prevailing winds in the region are generally from the southwest. These winds blow parallel to the coastline, which means that warm ocean currents are deflected away from the shore and towards the east. As a result, the waters off the coast of Christchurch are generally cooler than those further north or northeast. The position of islands such as New Caledonia and Norfolk Island can also influence the movement of warm ocean currents in the region. These islands help to direct the flow of warm water towards the Coral Sea and the Tasman Sea, rather than towards the coast of New Zealand. This means that Christchurch, which is located on the eastern coast of the South Island, is less likely to experience the effects of warm ocean currents.

Note: That oceanic currents and winds can be affected by a range of factors, including El Niño and La Niña events, which can cause changes in sea surface temperatures and alter the path of ocean currents. As a result, there may be some years when warm ocean currents do reach Christchurch, even if this isn't typically the case in normal years.

#Hope it helps!

Sucrose is not a simple sugar because it is made up of  both glucose and fructose so sucrose is called a disaccharide. Therefore, option (D) is correct.

What is simple sugar?

A monosaccharide, often known as a simple sugar, is a form of carbohydrate that cannot be broken down into smaller molecules of glucose and is thus readily absorbed by the body.

There are three primary kinds of simple sugars: glucose, fructose, and galactose. All of these sugars have the same chemical composition, but their structures are quite different from one another.

Sucrose on the other hand is a disaccharide composed of both glucose and fructose. Therefore, it is not a simple sugar and can be broken down into smaller or simpler molecules.
