Explanation:

According to this question, PKU (Phenylketonuria) is a recessive condition in humans. A normal human must possess at least a dominant allele in the gene.

In a situation where two normal parents produce a child with PKU. This means that both parents are heterozygous for the condition i.e Pp × Pp. Hence, the heterozygous male (Pp) will produce gametes in the following proportion: P (1/2) and p (1/2).

This means that the probability that a sperm from the father will contain the PKU allele (p) is 1/2 or 50%

Answer:

Explanation:

In Mirabilis jalapa also known as the 4'o clock plant, flower colour shows incomplete dominance that is why the F1 plant obtained by the crossing of pure Red flowered plant(RR) with pure white flowered plant(rr) shows pink flowers(Rr).

When F1 plant(Rr) is crossed is with pure white flowered plant (rr), the plant obtained would have a genotype of Rr and rr in ratio 2:2

While the phenotype will be 2 pink and 2 white at of 2:2

The phenotypic ratio of the offspring will be 2:2

Answer: Dendritic pattern

Explanation:

The drainage pattern that is shown in the picture above is referred to as the Dendritic pattern.

Drainage Pattern simply refers to the pattern that is formed by lakes, rivers, streams etc in a drainage basin. It should be noted that a dendritic drainage patterns look like the branch of a tree that has lots of twigs and they are usually formed in areas that has flat bedrock such as shale. Since the above diagram looks like the description here, the answer is a dendritic pattern.

Answer: ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells. ... Primary active transport directly uses a source of chemical energy (e.g., ATP) to move molecules across a membrane against their gradient.

Hope this helps... stay safe and have a great weekend!!! plz mark brainliest if i am right...

The role of ATP in the process of active transport is - It provides the energy that cells need to move molecules against a concentration gradient.

Active transport is the transport process where carrier proteins pick up specific molecules and take them through the cell membrane against the concentration gradient.

Thus, the role of ATP in the process of active transport is - It provides the energy that cells need to move molecules against a concentration gradient.

Answer:

Nothing is more important to us on Earth than the Sun. Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.

Explanation:

Without the energy of the Sun, there is no life possible on the Earth's surface. This is because the Sun is the only source of energy for plants and animals.

Energy may be defined as the power to do work to perform several metabolic activities by the organisms.

The energy of the Sun is captured by green plants in order to perform photosynthesis and make food. Through this process only, the oxygen will be available on the Earth's surface which is inhaled by other living organisms for the purpose of survival.

Without Sun, the earth looks like a ball of ice with coated rock and life less.

Therefore, it is well described.

Answer:

The figure is absent in this question, however, it can be answered based on general understanding of the structure of rough endoplasmic reticulum. The options are:

A) Structure Y contributes the raw materials required for the synthesis of proteins

B) Structure Y packages proteins for export from the cell

C) Structure Y is the location where proteins are synthesized

D) Structure Y contains enzymes that cut and bind proteins.

The answer is C.

Explanation:

The rough endoplasmic reticulum is one of the two types of the endoplasmic reticulum, which is a part of the endomembrane system found in eukaryotic cells. The rough endoplasmic reticulum is so named "rough" because of the structures attached to its surface.

The structures attached to the surface of the rough endoplasmic reticulum are the structures labelled Y in the figure of this question. Those structures are called RIBOSOMES and they are the site (organelles) of protein synthesis in living cells. Therefore, structure Y is the location where where proteins are synthesized.

Answer:

rough ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis)

Explanation:

rough ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis)

The proteins move from the rough ER to the transport vesicle and cisternae of the Golgi apparatus and, further with secretory or transport vesicle, are released from the cell surface (exocytosis). Thus, option A is correct.

The protein pathway (secretory) is the mechanism of the transportation of the newly synthesized proteins by ribosomes that are transported out of the cell. The proteins are first present on the ribosomes of the ER.

For post-translational modification proteins from rough ER are transported to the Golgi apparatus. From the Golgi vesicles and cisternae, the proteins are packed in the secretory or transport vesicles to the cell surface where they are thrown out of the cell by exocytosis.

Therefore, the pathway of the newly synthesized protein is rough ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis).

principal of genetics

For the trait of hair color, only one of the alleles from each parent gets passed down to the offspring because of the principle of segregation that is in the second option as segregation explains how the alleles are separated.

Mendel's law of segregation is very significant as it explains that during the formation of gametes, each parent will pass down only one allele for a given trait to their offspring, and each gamete receives unique genetic information from its parents. Through the law of segregation, the offspring that are produced are different from each other.

Hence, for the trait of hair color, only one of the alleles from each parent gets passed down to the offspring because of the principle of segregation that is in the second option as segregation explains how the alleles are separated.

Answer: Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

1. Development and growth

After meiosis has produced a gamete, and this has fused with another gamete to form an embryo, the embryo grows using mitosis. This growth continues throughout an organism’s life, in plants, animals, and fungi. In this way, the original chromosomal set is preserved.

2. Cell replacement

This occurs when the original cell is damaged or wounded. New cells are created to replace those that were damaged. Examples of this are the healing of a cut or a broken bone. When old cells die, new ones replace them to ensure continuing functionality.

3. Asexual reproduction

Single-celled organisms and certain multicellular organisms use mitosis for asexual reproduction. This includes reproduction by fragmentation, as in the case of planaria, and reproduction by budding, as in the case of sea anemones. Many plants reproduce using mitosis.

First, we need to understand what meiosis is. Meiosis is the replication of cells that results in each daughter nucleus containing half of the parent cell’s chromosomes. Meiosis is used primarily for the production of gametes, which are incorporated in sexual reproduction. Thus, the main difference between mitosis and meiosis is that mitosis produces somatic (body) cells, which can go on to become part of any bodily tissue, whereas meiosis only produces germ (sex) cells. Organisms which reproduce asexually cannot undergo meiosis, whereas all eukaryotic organisms undergo mitosis. Mitosis and meiosis are similar in that both can only occur in eukaryotic cells. This is because prokaryotic cells do not contain a nucleus within which to begin the processes of mitosis and meiosis. Instead, prokaryotes replicate themselves using binary fission. Both mitosis and meiosis begin with DNA replication in the parent cell to create four sets of chromosomes: in mitosis, these sets are split to form two diploid daughter cells, while in meiosis, these sets are split to form four haploid daughter cells. This is because cells undergo only one division in mitosis, whereas they undergo two divisions in meiosis.

Answer:

Plants undergo photosynthesis, which is the process where carbon dioxide, water, and sunlight are transformed into sugar and oxygen. Even though they look different than terrestrial (land) plants, aquatic plants, or plants that live on the water's surface or submerged underwater, also undergo photosynthesis.

The formation of sea ice removes freshwater and dissolved solids from seawater, leading to a decrease in density. The correct option is C.

The concentration levels of salts in water or soils are referred to as "salinity."

Salinity is classified into three types based on its cause: primary salinity (also known as innate salinity), secondary salinity (also known as dryland salinity), and supplementary salinity (also called irrigation salinity).

When the water table rises, natural salts rise to the surface; in sufficient quantities, these salts become toxic to most plants.

As a result, the surrounding seawater becomes saltier because salt is left behind when sea ice forms.

As seawater becomes saltier, its density rises and it begins to sink. Surface water is drawn in to replace sinking water, which eventually cools and salts enough to sink.

Thus, the correct option is C.
