Case study A man and woman are deciding whether to have a child. The genotype of the man includes a recessive allele for an inherited

Answers

Explanation: When both parents are carriers for a recessive disorder, each child has a 1 in 4 (25 percent) chance of inheriting the two changed gene copies. A child who inherits two changed gene copies will be “affected,” meaning the child has the disorder.

a. It appears to have cells when viewed under a microscope
b. It seems to react to being touched
c. It possesses a purposeful anatomical structure that differs from one another
d. It's body is bilaterally symmetrical

Answers

Answer: It's body is bilaterally symmetrical

Explanation:

The option that is not considered essential in determining whether the putative new life form shows the properties of life is that its body is bilaterally symmetrical.

The fact that the creature has cells signifies that it has life, reaction towards touch is also another factor that shows its has life.

We should note that its body shape doesn't signify I it has life or not. Therefore, the answer is D.

Describe the scientific theory of cells (cell theory) and relate the history of its discovery to the process of science.

Answers

Answer:

The cell theory states that all living organisms are made up of cells and each cell is the fundamental and functional unit of the living organism. The last point of the theory is that each cell is produced by a pre-existing cell.

The cell discovery was made by Robert Hooke with the help of the compact microscope was made by him. He observed the cell wall of the cell in cork and after him, many other scientists proved the presence of cells and presented evidence of the cell theory.

Picture yourself hiking in a narrow canyon in Utah. The canyon is dry and it hasn’t rained for weeks. You see some thunderhead clouds in the sky, but not one drop of rain all day.

Nevertheless, a small rush of water starts to run through the canyon, turning it into a creek. There must have been a heavy rainfall somewhere nearby. Water runs down the sides of the canyon, forming little waterfalls. You realize that there could be a flash flood coming! You turn quickly up a side trail to higher ground before you are washed down the canyon.

What are the stimulus and response in this scenario?

A. The stimulus is the rain clouds and the response is the water in the canyon.
B. The stimulus is the appearance of water in the canyon and the response is moving to higher ground.
C. The stimulus is water running down the canyon walls and the response is little waterfalls forming.
D. The stimulus is the rain somewhere else and the response is you realize that there could be a flash flood.

4. If you just finished exercising, what happens to the amount of carbon dioxide you
exhale?!

Answers

Answer:

More Carbon dioxide is removed from the blood and exhaled in the breath

Explanation:

During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it. So, when you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide.

When the ______________or signal molecule is attached, the door is open for certain ________________to enter the cell. These types of receptors are important in the _________________.

Answers

Answer:

ligand; ions; ligand; ions; nervous system

Explanation:

Ligand-gated ion channels are transmembrane protein complexes that open when they bind to their corresponding ligands (e.g., neurotransmitters). This type of receptor is known to modulate the synaptic transmission between neuron cells or neuron and muscle cells. In the nervous system, ligand-gated ion channels located at sites of synaptic contact determine the ion flow in response to neurotransmitter binding. Some examples of ligand-gated ion channels include gamma-aminobutyric acid A (GABA-A) and nicotinic cholinergic receptors.

A landform being broken apart is weathering erosion or deposition? and is a glacier forming from an accumulation of ice and snow is weathering and erosion or deposition? please help fast

Answers

Answer:

A landform being broken apart is WEATHERING.

A glacier forming from an accumulation of ice and snow is DEPOSITION

Explanation:

This is because weathering is the process where rocks or landforms are broken down into smaller pieces sometimes form soul through the activity of an agent which could be wind, water, ice, gravity e.t.c.

While Deposition is the accumulation of segments of particles in a new location forming another shape after it has been wash away(erosion) into that new location by water, ice, wind, gravity e.t.c.

You are solving a density problem, where density = mass/volume. Your volume of liquid is 2.1 milliliters. Your mass of the liquid is 2.811 grams. What is the density of the liquid using the correct number of sig figs?

Answers

Answer:

Density = 1.3386kg/m³

Explanation:

Given the following data;

Volume = 2.1 millimeters to meters = 2.1/1000 = 0.0021 meters

Mass = 2.811 grams to kilograms = 2.811/1000 = 0.002811 kilograms

To find the density;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the equation;

[tex]Density = \frac{mass}{volume}[/tex]

Substituting into the equation, we have;

[tex] Density = \frac {0.002811}{0.0021} [/tex]

Density = 1.3386kg/m³

What occurs in an updraft?

Answers

Answer:

D. Warm air from the south rises.

Explanation:

Updraft occurs when the warm air from the surface rises.

What is Updraft?

Updrafts occur when the warm air rises to the level when the process of condensation begins and precipitation starts to develop.

In a mature storm, updrafts are present alongside downdrafts that caused by cooling and falling of precipitation so we can conclude that updraft occurs when the warm air from the surface rises.

How are bacteria different from viruses?

B. Bacteria are eukaryotes.
C. Bacteria are not killed by antibiotics.
D. Bacteria can replicate themselves without help from a living cell.

Answers

Answer:

d

Explanation:

bacteria can replicate themselves without help from a living cell.

Bacteria are capable of self-replication without the assistance of a live cell. So, the correct option is D.

What is Bacteria?

Bacteria are ubiquitous, generally free-living creatures that are frequently made up of one biological cell. They make up a significant portion of the prokaryotic microbial kingdom. Usually a few micrometres in length, bacteria were among the earliest life forms to appear on Earth, and are ubiquitous in most of its environments.

Bacteria lack a nucleus bound to the membrane and other internal components and are consequently placed within the group of unicellular life-forms called prokaryotes. Prokaryotes have dominated life on Earth for at least three-quarters of its existence and have adapted to nearly all of the planet's biological niches. Bacteria are capable of self-replication without the assistance of a live cell.

Therefore, the correct option is D.
