Answer:

Autotrophs

Explanation:

They are the producers in the ecosystem.

Autotrophs are organisms that produce food food from sunlight or from inorganic substances via chemical processes.

They obatin their energy by converting very simple materials into complex and useful organic compounds for use in the ecosystem. One of such process is photosynthesis in which green plants uses sunlight and carbondioxide to produce glucose for their nourishment. Another of such process is chemosynthesis.

Most heterotrophs(consumers) relies on this source of energy for their own survival and nourishment.

1. List five observations Darwin made about the Amblyrhynchus lizards.

a. They measure about 2-3 feet long.
b. They are cold-blooded.
c. They feed on crab and sea lion feces.
d. They are the only marine iguanas in the world.
e. Their nostrils are connected to salt glands that allow them to expel excess sea salt.

2. Describe two examples of structural adaptations that Darwin observed.

a. Darwin discovered that finches in the Galapagos have thirteen different kinds of beaks.
b. Darwin observed two kinds of giant tortoises that are distinguished by the shapes of their carapaces (dome-shaped and saddle-shaped).

3. Describe two behavioral adaptations that Darwin observed.

a. The marine iguanas have developed several ways of coping with the cold. At night, they huddle together for warmth.
b. In the face of famine, the marine iguanas have adapted by having the ability to shrink their body size. They are able to grow back to their original size once the food is supply increases.

4. Explain how these observations influenced his theory of evolution?

These observations led Darwin to believe that if a certain trait is more advantageous in a specific environment, then the carriers of that trait are more likely to survive into adulthood and to generate offspring than those who do not have that trait. Eventually, the advantageous traits for a species will proliferate. Darwin later called this as "survival of the fittest".

For this week's CRQ, you are to design your own genetic cross between a female and a male. Be sure to include each of the follow

svp [43]

Answer and Explanation:

Punnett squares are illustrations that display the product of hybrid trait crosses by genetic breeding. Established parent genotypes and phenotypes are used and are usually compatible with Mendelian ratios and inheritance. The phnomenon influencing this behaviour is the

Law of Segregation,
Law of Independent assortment
and Dominance

For this cross...

Assuming Widow's peak= dominant

1. What are the dominant and recessive traits in cross?

Parent generation or P generation:

gametes: Ww → Widow's peak dominant (W), No Widow's peak recessive (w)

2. Is the male homozygous dominant, homozygous recessive, or heterozygous?

Heterozygousity describes the allelic makeup; these traits are made of two different forms of the same gene.

Male: Ww → with the W.peak;

(Thus, with both W and w this is a heterozygous trait)

3. Is the female homozygous dominant, homozygous recessive, or heterozygous?

However, homozygous traits are made up of the same forms of the gene called alleles.

Female: ww → without the W.peak

(Thus, with both w ad w this is a homozygous trait)

1. genotypes and phenotypes for parent and offspring...

Assuming heterozygousity of the male , for the cross

P generation: Ww× ww

Widow's peak ×No Widow's peak

F1 generation:

genotype: Ww × ww ...(from punnet square)
phenotype: 2 with the W.peak; 2 without

∴ 50% are genotypically heterozygous while 50% is homozygous , 2 with the W.peak; 2 without

in a way everything we eat depends on photosynthesis describe how a breakfast of bacon and eggs depends on photosynthesis

Leokris [45]

Both chickens and pigs are omnivores so they eat scrap, grain, and most importantly for this subject vegetables and fruits. Vegetables and fruits both came from photosynthesis, so when we eat bacon and eggs we are eating pigs and chickens that ate plants and vegetables that gained energy due to photosynthesis. At least that’s what I think

Jason is in middle school and is well below normal height for his age. which hormone might be in short supply in jason's body?

Zolol [24]

Given that Jason, middle school boy, is well below normal height for his age, it is possible that Human Growth Hormone might be in short supply in his body. Growth hormone (hGH) is also called Somatotropin. This hormone is responsible for the stimulation of growth, cell reproduction, and cell regeneration in humans.
