Answer:

A

Explanation:

Studying amino acid sequences would provide the best evidence that two organisms share a common ancestor.

Amino acid sequence is a series of bases with different letters usually four(A T C G or U)  this letter contains information of an individual when translated.

The amino acid sequence of 2 or more individuals can be compare to each other through the process called Blasting using a tool called Blast

For organisms that are phylogenetically close i.e related by an ancestor, there will be similarities between their DNA sequences when compared. The amino acid sequence of an individual contains the information of the individual and it is unique for each individual.

Hence, amino acids sequence provides the best evidence of organisms sharing a common ancestor.

Answer: Overview of the Calvin cycle

In the Calvin cycle, carbon atoms from CO2​start text, C, O, end text, start subscript, 2, end subscript are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions.

Answer:

C

Explanation:

Answer:

D. allows the recombination of genetic information.

The main difference that separates prokariotic organisms from eukaryotic organisms is the organisation of the genetic material. Prokaryotes have a single chromosome that isn't separated by a membrane and it's called nucleoid. Eukaryotes have multiple chromosomes that are inclosed in a nuclear envelope(nucleus).

The only organelles present in prokaryotic cells are the ribosomes(70S) which differ from the eukaryotic ribosomes(80S). Eukaryotic cells have membrane bound organelles like the mitochondrion or Golgi aparatus.

Explanation:

Answer:

I dont see any diagram but in general, the organelles are the nucleus, ribosomes, ER, golgi apparatus, and vesicles

Explanation:

The nucleus contains the genetic code and creates the "orders" for the ribosomes

The ribosomes synthesize the proteins

The (rough) endoplasmic reticulum contain ribosomes

The golgi apparatus and vesicles transport and modify proteins

The answer is A

Answer:

sugars are not related to lipids

Answer:

The higher the pressure on anything, the hotter it will get.  The hotter a rock gets, the more possibility that it will have to melt.

So you're out the base of the crust, with any kilometers of crust above you, and that's a lot of pressure.  Then take into account that you have thousands of degrees of heat coming from the mantle-core boundary, and directly from radioactive decay within the mantle, which only adds to the temperature.

The net result is like melting a stick  of butter.  It's very easy to do without a lot of energy -- since Earth is a massive ball of thermal energy, then well... it's easy to do.

Answer:

Nitrogen is a naturally occurring element that is essential for growth and reproduction in both plants and animals. It is found in amino acids that make up proteins, in nucleic acids, that comprise the hereditary material and life's blueprint for all cells, and in many other organic and inorganic compounds.

2. Plant cell

3. Plant cell

4. both

5. Plant cell

6. Both

7. Both

Explanation:

Plant cells have a cell wall and a cell membrane, unlike animal cells that only have a cell membrane.

Both have a cytoplasm, vacuole, mitochondria, and a nucleus.

Hope this is correct. Good luck with your studies.

Both plant cell and animal cell have a nucleus, mitochondria, cytoplasm, and cell membrane. Only a plant cell have cell wall, chloroplast and vacuole.

Plant cells are the unit of plants. These cells are present in all green and non-green cells in a plant. However, an animal cell is the fundamental unit of an animal. Different types of animal cells make up an organism.

Plant cell contain an outermost covering called the cell wall. It protects them from shock and provides mechanical strength to the cell. It is absent in the animal cell.

Chloroplast is also present in the plant cells whereas it is absent in the animal cells. It is a double-membranous structure. A chloroplast is responsible for the process of photosynthesis as it contains chlorophyll pigment. A vacuole is also present in the plant cell and absent in an animal cell. The vacuole is responsible for the storage of reserved food materials in the form of complex sugars.

Answer: Cellular respiration

Explanation:

Pea plant has Round Seed dominant over Wrinkled Seed.

Round Seed allele is R

Wrinkled Seed allele is p

Hom.ozygous Dominant Alleles: RR (Round Seed)

Heter.ozygous Dominant Alleles: Rr (Round Seed)

Hom.ozygous Recessive Alleles: rr (Wrinkled Seed)

Whenever we cross Heter.ozygous Dominant(Rr) with Hom.ozygous recessive (rr), we get 50% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,

The P1 is Rr

The P2 is rr

When we cross them,

It has 4 offsprings,

Rr Round Seed

Rr Round Seed

rr Wrinkled Seed

rr Wrinkled Seed

Thus the answer is 50% round seed as there are 2 out of 4 heter.ozygous dominant round seed.

Whenever we cross Hete.rozygous Dominant(Rr) with another Heter.ozygous Dominant (Rr), we get 75% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,

The P1 is Rr

The P2 is Rr

When we cross them,

It has 4 offsprings,

RR Round Seed

Rr Round Seed

Rr Wrinkled Seed

rr Wrinkled Seed

Thus the answer is 75% round seed as there are 3 out of 4 hom.ozygous and hete.rozygous dominant round seed.

Whenever we cross Homo.zygous Dominant(RR) with Heter.ozygous Dominant (Rr), we get 100% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,

The P1 is RrR

The P2 is Rr

When we cross them,

It has 4 offsprings,

RR Round Seed

RR Round Seed

Rr Wrinkled Seed

Rr Wrinkled Seed

Thus the answer is 100% round seed as there are 4 out of 4 hetero.zygous and homo.zygous dom.inant round seed.

According to The Cornell Lab, "Birds do not have teeth, however, they may have ridges on their bills that help them grip food, but this does not count as teeth. So what about birds that have “tooth” in their name, like Double-toothed Kite? Some birds of prey have a sharp ridge or “tomial tooth” on the bill that they use to bite into their prey when subduing it. But these modifications to the bill surface are not considered the same thing as individualized teeth seen in other animals."
