Mark and Michelle both have dark hair, which is a dominant trait. But their first child is blonde. Which is the most likely explanation

Answers

Answer 1
Both parents have a recessive blonde allele that got passed on to their child.

Another gene caused the alleles for brown hair to deactivate.

It's not possible--Mark can't be the real father.

One of the two has a blonde allele that is dominant in the child.
Answer 2

Answer:

They are heterozygous for the dark hair.

Answers

Answer:

The electrical charge of a particle is called an electric charge.

Explanation:

Electricity always comes in units of the Coulomb, which is the unit of measurement for electric charges. One Coulomb is defined as follows: "the quantity or magnitude of electricity carried by an electron in the electrostatic field around a point on the Earth with coordinates (latitude, longitude)". We can use units like volts and amperes to communicate this kind of data now, but typically you'll see it written as Cs.  

To do some simple arithmetic with these units you need to know that one Couloth will equal 93 millimeters squared per second times per second (mC/s*ms).

Most ecosystems support only a few different species.
Invasive species rarely survive in new ecosystems.

Answers

Answer:

A) they greatly disrupt existing food webs.

Explanation:

Invasive species change the food web in an ecosystem by destroying or replacing native food sources.

Answer:

Option 1: They greatly disrupt existing food webs.

Explanation:

Invasive species: As the name suggests, any organism which is not native to the habitat and disrupts the growth of the existing ecosystem where it invades or is introduced are called invasive species.Examples of invasive species: Red Lionfish, Green Iguana, Longhorn Beetle.Characteristics of invasive species:High tolerance to an adverse environment,Rapid reproductive rate.Enhanced adaptability.Increased dispersal ability.Invasive species have the ability to cause extinction or threat to the native plants and animals. They can also cause destruction to the natural resources found in the place. Harming economic and ecological growth.

3. Would a cliff in the desert or a cliff along the seashore experience more weathering? Explain your answer.​

Answers

Answer:

A sea shore would have more weathering, because the gust of wind from the shore line will surley weather out the mountain, including the waves washing out rocks.

Explanation:

Pls give brainliest

A seashore would experience more weathering than the desert. This is because of the gust of wind on the cliff of the mountain.

What is Weathering?

Weathering can be considered as the breaking down or dissolving of rocks and minerals on the Earth's surface. Once a rock or mineral has been broken down by the process called erosion, it transports the small bits of rocks and minerals away from each other. Water, acids, salt, plants, animals, and change in temperature are all the agents of weathering and erosion.

A cliff along the seashore would experience more weathering, because of the gust of wind from the shore line. This will surely weather out the mountains, including the waves washing out the rocks and minerals.

Why do most food chains only two, three or rarely ,four consumers after the green plant producer?

Answers

Answer:

It is rare to find food chains that have more than four or five links because the loss of energy limits the length of food chains. At each trophic level, most of the energy is lost through biological processes such as respiration or finding food

Explanation:

Answer:

Because so much energy is lost to life processes.

Explanation:

As you progress through each trophic, each organism on that level loses energy gained from the previous trophic. This is due to losing energy through wasted material (e.g. bones) and to life processes, 7 of which can be remembered by MRS GREN:

M ovement

R espiration

S ensitivity

G rowth

R eproduction

E xcretion

N utrition

This means that each time, energy is wasted and lost from the food chain. More than four trophics would result in so much energy being lost from the initial trophic (producer), that it would be largely pointless!

Drag each item to indicate whether it exhibits fracture or cleavage.​

Answers

Answer:

From left to right

Explanation:

Cleavage, cleavage, fracture

The first item exhibit a cleavage. The second item exhibit a cleavage. The third item exhibit a fracture.

In mineral science, Cleavage is the process by which a mineral breaks or splits through smooth planes with a pattern because the material is stratified in a layered pattern. It generally seems regular since it fractures along its plane of weakness.

A fracture happens when a mineral splits with fractures and does not produce a particular definite shape. It frequently emerges in an erratic and irregular pattern.

From the three picture given, the first and the second item exhibit cleavage, and the third item exhibit fracture.
