Cell membrane: controls what goes in or out, it’s like a guard (in all cells)

Cell wall: provides shape and support (only in plant cells)

Nucleus: cell’s control center, largest structure inside the cell, contains deoxyribonucleic acid (DNA)

Lysosomes: small structures that contain chemicals for breaking down food and waste for use or disposal (like a garbage truck)

Vacuoles: large sacs thats stores food and water (like a grocery store)

Endoplasmic reticulum: a maze of passageways that transport materials through the cell, has rough E.R. (has ribosomes) and has smooth E.R. (doesn’t have ribosomes)

Golgi apparatus: organelles that package and distribute proteins throughout the cell

Chloroplasts: green structure that convert the sun’s energy into food (carbohydrates), only found in plant cells

Helppppppp plz thx........
8090 [49]

Answer:

1) aa- affected

2) Aa- unaffected carrier

3) aa- affected

4) aa- affected

5) Aa - unaffected carrier

6) Aa- unaffected carrier

7) aa- affected

8) aa- affected

9) Aa- unaffected carrier

10) aa- affected

11) Aa- unaffected carrier.

This trait is <em>recessive</em>.

The F1 generation has a 50/50 chance of having unaffected offspring.

Explanation:

1) Given

2) Some of the offspring have the trait, and they're not affected, so they have to be a carrier

3) The box is shaded in so they have to have the trait, which means they have to have the same gene pattern as the other affected person (#1)

4) They are also shaded in, so they have to have the trait

5) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

6) Same reasoning as #5

7) This is shaded in, the box has to have the trait

8) Shaded in = has the trait/affected

9) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

10) Shaded in = has the trait/affected

11) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

Since the trait is displayed when the people have two lowercase letters (aa), and people can be unaffected and carriers, (Aa), this trait has to be recessive.

If you make a Punnett Square, you will see that half of the offspring can result in an Aa, while the other half can result in an aa, meaning there's a 50/50 chance of the offspring of the F1 (first) generation will have the trait.

All organisms in an ecosystem are interrelated by the abiotic and biotic resources they use in the course of their lives:
jonny [76]

<span>a)      </span>The milkweed is the primary producer in the ecosystem. It manufactures food from the abiotic factors in the soil such as nitrates and water and those in the atmosphere such as carbon-dioxide and sunlight. The milk weed is then fed on by the caterpillar and a primary consumer. The caterpillar is then fed on the mocking bird (secondary consumer)

<span>b)      </span>Increased human population growth and their activities have resulted in the emission of carbon dioxide and other greenhouse gases in the atmosphere. This has increased the global temperature. This increase of global temperature increase ocean temperatures causing coral bleaching.

Another example is depletion of water sources by human activities hence causing drought. Drought reduces the amount of vegetation growth due to scarcity of water in the soil (due to lowering of the water table) for plant growth.

(last question) #5<br> Describe the different body senses and how they function.
Bad White [126]

Answer:

Those senses are sight, smell, hearing, taste, and touch. We see with our eyes, we smell with our noses, we listen with our ears, we taste with our tongue, and we touch with our skin. Our brain receives signals from each of these organs, and interprets them to give us a sense of what's happening around us.
