Primary roots are thin and spread downward.

What are Primary roots?

Primary roots are the first roots to develop from a seedling. They are generally thicker and longer than the secondary roots that develop later. Primary roots are responsible for anchor the plant into the soil and absorbing water and minerals from the soil to support the growth of the plant.

Primary roots are the initial roots that grow out of germinating seeds. These roots are thin and spread downward in order to anchor the plant in the soil and absorb water and minerals. They also help the plant to access deeper layers of soil where more nutrients may be found. Primary roots are usually short-lived and are eventually replaced by secondary roots.

Hence, option B is correct.

A hurricane is a type of storm called a tropical cyclone, which forms over tropical or subtropical waters. ... When a storm's maximum sustained winds reach 74 mph, it is called a hurricane. The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating, or category, based on a hurricane's maximum sustained winds.

Hope this helps

Answer: A tropical cyclone is a rotating low-pressure weather system that has organized thunderstorms but no fronts (a boundary separating two air masses of different densities). Tropical cyclones with maximum sustained surface winds of less than 39 miles per hour (mph) are called tropical depressions. Those with maximum sustained winds of 39 mph or higher are called tropical storm

1) If the individual with the dominant phenotype has a parent with the recessive phenotype, the genotype of the individual is heterozygous (Aa).
2) If the individual with the dominant phenotype has offspring with the recessive phenotype, the individual must be heterozygous (Aa).

The two situations on a pedigree that would allow you to determine the genotype of an individual with the dominant phenotype.

By analyzing the presence of the recessive phenotype in the parents or offspring of an individual with the dominant phenotype, we can determine their genotype as heterozygous (Aa).

If high amounts of product in the samples, '+++' , correlates with optimal temperatures and pH for enzyme activity, then...

Explanation:

Enzymes are specialized proteins that function as biological catalysts- they speed up chemical reactions. As proteins, these are susceptible to changes in temperature and pH- they function best at optimal values for both conditions, but can be denatured, rendering them inactive at relative extremes.

Each enzyme provided has its own optimal temperature and pH values.

Thus from the table A- pepsin, B- Amylase and C- thermophilic enzyme can be hypothesized.

Answer:

Explanation:

Nuclear receptors are a type of protein that functions as an intracellular steroid and thyroid hormone receptor. The interaction of these hormones in conjunction with nuclear receptors changes the pattern of gene expression, allowing certain genes to be transcribed while others are silenced.

As a consequence, unique mRNA translation products, proteins, and, in most cases, enzymes are generated. Nuclear receptors connect to DNA directly and control the expression of certain genes, regulating the organisms growth, homeostasis, and metabolism.

The following domains are found in a normal nuclear receptor:

The amino-terminal activation domain contains the transcriptional activation mechanism and is strongly variable in sequence (AF1). The recruiting of coregulators is the domains key feature.

⇒ Activation function 1 (AF1); Coregulator recruitment

DNA binding domain: It is amongst the most closely conserved centrally located domains, with two zinc fingers that attach to specific DNA sequences known as hormone reaction components (HRE).

⇒ nine conserved cysteine residues; zinc finger domain; center of the receptor.

The hiinge domain serves as a versatile connection between the DNA binding and ligand-binding domains. It has a nuclear localization signal in it. ⇒ Nuclear localization signal

Ligand binding domain:  The sequence of the ligand-binding domain is moderately conserved throughout nuclear receptors. It denotes the carboxyl-terminal end of a ligand domain. It has hydrophobic steroid-binding pockets that draw the hormone and AF2 activation domains. It also attaches to proteins that serve as coactivators and corepressors.

⇒ binding of corepressor proteins;  steroid-binding hydrophobic pocket; AF2 activation domain; binds coactivators; carboxyl-terminal end

Osmosis is a process that helps cells maintain homeostasis by regulating the movement of water molecules across their membranes. Option A is the correct.

Through the movement of water molecules, osmosis helps maintain an equilibrium of substances inside and outside a cell. When there is a difference in the concentration of solutes (substances dissolved in water) on either side of a cell membrane, water molecules will move from an area of lower solute concentration to an area of higher solute concentration. This movement of water helps to equalize the concentration of solutes on both sides of the membrane, maintaining a balance and preventing the cell from becoming too dilute or too concentrated.

For example, if a cell has a higher concentration of solutes inside compared to the outside, water molecules will move into the cell through osmosis, increasing the volume and preventing the cell from shrinking. On the other hand, if the concentration of solutes outside the cell is higher, water molecules will move out of the cell, preventing it from bursting.

In summary, osmosis helps cells maintain homeostasis by regulating the movement of water molecules to achieve an equilibrium of substances inside and outside the cell.

Simply the noise from heavy traffic will cause the destructive interference which reduces the echolocation,blocking the echoes  and therefore prevent prey location for bats.

Generally this reduces the Bats' population, as some could not rely on the echo to locate the prey, leading to starving  and death. Thus each bat needs to rely on the individual echolocation from the prey to survive as new hunting adaptation.Since the echolocations has been blocked

Answer:

Bats would be unable to use echolocation, which would prevent them from finding any prey.

Biology > Human biology > Central Nervous System + Peripheral Nervous System

The central nervous system (CNS) consists of the brain and spinal cord. While the peripheral nervous system (PNS) consists of the nerves that leave the spinal cord and go to other parts of the body.

First, PNS nerves pick up information from organs (e.g., the temperature of the environment through skin nerves) and sends it to the CNS.

The CNS then processes the information and sends the orders to the body's organs through the PNS. Therefore, the answer is A.

Explanation:

The resting phase of the cell cycle is called interphase.

Interphase is a critical stage in the cell cycle during which the cell prepares for division by going through different activities such as growth, DNA replication, and protein and organelle production. It is the longest phase of the cell cycle and is separated into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

The cell develops in size, synthesises RNA and proteins, and performs its regular duties during the G1 phase. The cell enters the S phase after passing through the G1 checkpoint. The DNA of the cell is reproduced during the S phase, resulting in the production of two identical copies of each chromosome.

This ensures that during cell division, each daughter cell receives a complete set of genetic material. The cell enters the G2 phase after DNA replication, where it continues to expand and prepares for mitosis.

Interphase is not a real resting phase because the cell is actively engaged in multiple cellular functions. However, because the cell is not visibly dividing at this period, it is commonly referred to as the resting phase.

Answer:

Evidence of fossil apes and hominids in both East and West of the great rift valley

Explanation:

The East Side Story hypothesis opined that a tectonic plate movement created a seismic split in the earth, thus deepened the rift valley and created a geographical barrier between the east and the west of the great rift valley. The barrier created a kind of geographical isolation between the ancestors of hominids, dividing them into two with each population taking different evolutionary paths.

Thereafter, the ancestors in the western side of the rift valley evolved into the chimpanzee's family while those in the eastern side ultimately evolved into humans.

Thus, providing the fossils of apes and that of hominids in both East and West sides of the great rift valley will render the hypothesis invalid.
