During DNA replication, the ____ strand is assembled in the ____ direction from helix unwinding and is synthesized by ____ replication.

Answers

Leading Same Continuous

Explanation:

;)

During DNA replication, the leading strand is assembled in the same direction from the helix unwinding and is synthesized by continuous replication.

What is DNA replication?

The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the most crucial component of biological inheritance.

Because each of the two copies of DNA has one strand that is old and conserved and the other is newly created at the time of replication, this process is known as semiconservative replication.

Thus, during DNA replication, the leading strand is assembled in the same direction from the helix unwinding and is synthesized by continuous replication.

Answers

Answer:

d

took the test

Explanation:

Large seeds advantages:

They have a higher chance of germination and thriving.

Large seeds disadvantages:

They can not easily spread to new areas.

Small seed advantages:

They can spread easier to new areas.

Small Seed disadvantages:

They have a lower chance of surviving.

Large and small seeds main difference resides in their structure. The structure allows them to survive or to cover new areas. The disadvantage is that it can only do one of the two things.

Large seeds, as they are larger:

They have a structure that allows them to store more energy than small seeds. As a consequence, they have more elements to thrive and grow into a plant than small ones.Due to their size, they are heavier. They do not spread as far as the others.

Small seeds :

They do not have enough energy to grow, so they need more aid from the environment than large ones. In other words, their chances of survival are lower.The advantage is that they can colonize wide areas due to their lightness. So, even though they are small, they spread easier and cover more territory than large seeds.

To sum up, small seeds have a lower chance of survival, but they are more and cover longer distances. While large ones have a higher chance of survival, but they are fewer and cover short distances.

The diploid phase of the life cycle begins with the formation of the zygote.

Meiosis is referred to the type of cell division which occurs in the production

of male and female sex cells. This also occurs during sexual reproduction.

Parent cells provide male and sex cells such as sperm and egg which

contains DNA. They then fuse together to form a zygote which is the diploid

phase as a result of the fusion of two haploid cells. The zygote then

continues to undergo some meiotic processes which reduces it to back to a

From a plant cell leucoplast is removed. What will its effect be on the cell functioning?.

Answers

Answer:

Leucoplasts (λευκός leukós "white", πλαστός plastós "formed, molded") are a category of plastid and as such are organelles found in plant cells. They are non-pigmented, in contrast to other plastids such as the chloroplast.

Leucoplasts, specifically, amyloplasts

Lacking photosynthetic pigments, leucoplasts are not green and are located in non-photosynthetic tissues of plants, such as roots, bulbs and seeds. They may be specialized for bulk storage of starch, lipid or protein and are then known as amyloplasts, elaioplasts, or proteinoplasts (also called aleuroplasts) respectively. However, in many cell types, leucoplasts do not have a major storage function and are present to provide a wide range of essential biosynthetic functions, including the synthesis of fatty acids such as palmitic acid, many amino acids, and tetrapyrrole compounds such as heme. In general, leucoplasts are much smaller than chloroplasts and have a variable morphology, often described as amoeboid. Extensive networks of stromules interconnecting leucoplasts have been observed in epidermal cells of roots, hypocotyls, and petals, and in callus and suspension culture cells of tobacco. In some cell types at certain stages of development, leucoplasts are clustered around the nucleus with stromules extending to the cell periphery, as observed for proplastids in the root meristem.

Etioplasts, which are pre-granal, immature chloroplasts but can also be chloroplasts that have been deprived of light, lack active pigment and can be considered leucoplasts. After several minutes exposure to light, etioplasts begin to transform into functioning chloroplasts and cease being leucoplasts. Amyloplasts are of large size and store starch. Proteinoplasts store proteins and are found in seeds (pulses). Elaioplasts store fats and oils and are found in seeds. They are also called oleosomes.

which hormone signals the breakdown of glycogen in the liver increasing glucose in the blood?

Answers

Answer:

The answer is glucagon

Explanation:

When the blood sugar level drops down, the glucagon hormone converts the glycogen into glucose and raises its level in the bloodstream.

Glycogen is a main source of energy for the body. Glycogen is stored in the liver. When the body needs more energy, certain proteins called enzymes break down glycogen into glucose. They send the glucose out into the body.

Which hormone stimulates the breakdown of glycogen in the liver into glucose?

Glucagon's role in the body is to prevent blood glucose levels from dropping too low. To do this, it acts on the liver in several ways: It stimulates the conversion of stored glycogen (stored in the liver) to glucose, which can be released into the bloodstream.

How does glucagon increase blood glucose?

When your blood glucose levels trend lower or fall too low (hypoglycemia), your pancreas releases more glucagon. Glucagon helps blood glucose levels rise back up in multiple ways, including Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream.

Answers

Answer:

Human blood-red and not blue because Hemoglobin contains iron that gives the blood the red color when exposed to oxygen. The correct option is c.

What is hemoglobin?

Hemoglobin is a red color pigment that is present in the blood. It contains a heme group that carries oxygen into the body and carries carbon dioxide outside the blood. It is red and in some animals, it is blue because of copper.

Hemoglobin is made up of four protein chains that each bind an additional ring-shaped chemical structure called heme. Our red blood cells are red because of the heme groups in hemoglobin. In turn, our blood is red because of the millions of red blood cells that it contains.

Therefore, the correct option is c. Hemoglobin contains iron that gives the blood a red color when exposed to oxygen.

in aerobic respiration, what is the ultimate fate of the electrons released from the breakdown of glucose?

Answers

Answer:

They are combined with oxygen and hydrogen ions to form water.

Explanation:

The electron released from the breakdown of glucose transfers in the electron transport chain and is used in the formation of a proton gradient across the membrane.

What is aerobic respiration?

In the presence of oxygen gas, cells undergo cellular respiration, which is how energy from food is produced. The majority of plants, animals, birds, humans, and other mammals all engage in this sort of respiration regularly. As byproducts of this process, water and carbon dioxide are created.

The energy that was stored in carbohydrates and lipids during photosynthesis is released during the process of aerobic respiration and made available to living things. Glycolysis, the link reaction, the Krebs cycle, and oxidative phosphorylation are the four phases.

Protons are pushed out of the matrix and into the intermembrane space as a result of the electrons moving through the electron transport chain. The electrons eventually reach oxygen, which reacts with protons to create water.
