PlZ help Are enzymes specific or not

Pedigrees are normally used to represent simple dominant and recessive traits.

Pedigrees are drawn using standard symbols and formatting.

By analyzing a pedigree, we can determine genotypes, identify phenotypes, and predict how a trait will be passed on in the future.

Pedigree meets the low price check off on your list.

Scientists have devised another approach, called pedigree analysis, to study the inheritance of genes in humans.

1. The cells in our bodies are surrounded by these types of solutions.

slamgirl [31]

Answer:

1. The cells in our bodies are surrounded by these types of solutions. → Isotonic solution.

3. When an animal cell is places in this solution, it will burst (get layer) → Hypotonic solution.

4. When an animal cell is placed in this solution, it will shrivel or shrink (get smaller) → Hypertonic solution.

Explanation:

The cells in the body are in a balance of substances —concentration of solutes— between their cytoplasm and the extracellular space. This balance is dynamic in living beings, due to the constant exchange of ions and substances between the intracellular and extracellular space. For this reason, the extracellular medium is isotonic with the cytoplasm.

A cell can lose or gain water depending on the amount of solutes that a medium has in which it is found, with respect to the cytoplasm. This difference in solutes concentrations produces an osmotic gradient that drags water from the least concentrated solution to the most concentrated, through the process of osmosis, which seeks to achieve an equilibrium of concentrations.

When a animal cell is exposed to a hypertonic solution —with a higher concentration of solutes— it loses water and tends to dehydrate and become smaller.
An animal cell in a hypotonic solution receives water, so it can expand and even burst.

In practice, the concentrations of intracellular and extracellular solutes depend not only on the osmotic gradient, but also on the concentration gradient of substances.

_________ refers to the movement of air into and out of the lungs

jarptica [38.1K]

Answer:

Ventilation (Pulmonary) AKA Breathing

Explanation:

Pulmonary ventilation is often known as breathing. It is the means through which air moving into the lungs in the course of inspiration (inhalation) and away from the lungs at expiration (exhalation). Air flows as a result of variations in pressure between the atmosphere and the gases within the lungs.

Air, just like gases, moves from a zone of larger pressure to a zone of smaller pressure. Muscular breathing activities and recoil of elastic tissues forms the variations in pressure that causes ventilation. Pulmonary ventilation employs three seperate or distinct pressures:

-Atmospheric pressure

-Intraalveolar (intrapulmonary) pressure

-Intrapleural pressure

-Atmospheric pressure is the air pressure that is not from within but from outside of the body.

-Intraalveolar pressure is the pressure within the lungs alveoli.

-Intrapleural pressure is the pressure present in the pleural cavity.

These three pressures are important for pulmonary ventilation.

What is the solubility of NH4Cl at approximately 50.0 oC?

Semenov [28]

We can define the solubility as the maximum amount of solute (which may be a solid, liquid or gas) that is dissolved in a solvent ( which may be a solid, liquid or gas).
The solubility of Ammonium chloride (NH₄Cl) at 50°C is 50 grams, because the solubility of NH₄CL is 50g /100g of water at 50° C.

A particular viral genome can replicate in 8 hours. If you start with 55,000 copies of this genome, about how many copies would

deff fn [24]

If a viral genome can replicate in 8 hours and the starting copies is 55,000, the number of copies after 48 hours would be 3,360,000 copies

<h3>Replication rates</h3>

The starting number is 55,000 and replication happens every 8 hours.

Starting from 0 hours, the genome would 55,000

After 8 hours = 55,000 x 2 = 110,000 copies

After 16 hours = 110,000 2 = 220,000 copies

After 24 hours = 220,000 x 2 = 420,000 copies

After 32 hours = 420,000 x 2 = 840,000 copies

After 40 hours = 840,000 2 = 1,680,000 copies

After 48 hours = 1,680,000 x 2 = 3,360,000 copies
