blood enters on the left side of the heart through the_____ and enters the left atrium. Then passes through the_____ to enter the left ventricle 

Answers

Answer 1

Blood enters on the left side of the heart through the pulmonary veins and enters the left atrium. Then passes to the mitral(bicuspid valve) to enter the left ventricle.

Answer 2

Blood is a fluid component of the circulatory system that is very vital for transporting oxygen and nutrients in the body system. It comprises cells suspended in plasma.

The correct answers for the blanks are:

Blank 1: Pulmonary veins

Blank 2: Bicuspid valve

The blanks can be explained as:

The left side of the heart has an atrium that gets the oxygenated blood from the lungs through the pulmonary veins.

Oxygenated blood from the left atrium flows to the left ventricle.

Blood from the left ventricle flows to the aorta that distributes the oxygenated blood to the body parts.

The human digestive system consists of the gastrointestinal tract with the accessory organs of digestion which involve breaking down food into smaller and smaller components until they can be absorbed and assimilated into the body.

The GI tract consists of series of hollow organs which is joined in a long, twisting tube from the mouth to the anus. The processes of digestion consists of six processes:-

1. Ingestion

2. Propulsion

3. Mechanical or physical digestion

4. Chemical digestion

5. Absorption

6. Defecation.

In shorthorn cattle, when a red bull (RR) is crossed with a white cow (WW), all the offspring are roan—a spotted, red and white color. What offspring are expected from mating a roan bull and a roan cow?

Answers

Answer:

25% red

50% roan

25% white

Explanation:

When RR (red) is crossed with WW (white), it results in roan color.

       RR (red)   x    WW (white)

              RW (roan)

Two roan individuals are then mated.

          RW    x    RW

       RR    RW    RW    WW

Offspring

1/4 RR - Red

1/2 RW - Roan

1/4 WW - White

Hence, the offspring are expected to be 25% red, 50% roan, and 25% white.

What is amino acid?

Amino acids are molecules that form proteins when they combine. The building blocks of life are amino acids and proteins.

Amino acids are left over after proteins are digested or broken down. To help the body, the human body uses amino acids to make proteins: Food should be broken down.

A codon is a three-nucleotide (DNA or RNA) sequence that forms a unit of genomic information encoding a specific amino acid or signaling the end of protein synthesis (stop signals).

There are 64 different codons, 61 of which specify amino acids and three of which serve as stop signals.

The amino acid sequence for the given template will be:

3' AGGUUACCGAAUAAACGU 5'

So, as per three letter code, the amino acid chain will be:

Arginine – Leucine - Proline – Asparagine – Lysine – Arginine

Describe the steps of protein synthesis in a eukaryote.

Answers

The first step in protein synthesis is transcription. The transcription consists of the synthesis of messenger RNA by an enzyme(RNA-polymerase). This process takes place inside the nucleus.

The second step is  translation the mRNA exits the nucleus and binds to a ribosome. Ribosomes are the sites of protein synthesis. For every three nitrogenous bases of the mRNA an amino-acid is synthesized. Amino acids are brought to the protein synthesis site by transfer RNA. From this process we are left with a polypeptide.

Transcription is the initial stage of the production of proteins. The process of transcription involves an enzyme producing messenger RNA (RNA-polymerase). The nucleus is where this process occurs.

What is protein synthesis in a eukaryote?

The mRNA exits the nucleus and attaches to a ribosome in the second step of translation. Protein synthesis takes place in ribosomes. An amino acid is created for every three nitrogenous bases in the mRNA.

Transfer RNA transports amino acids to the location where proteins are synthesized. We are left with a polypeptide after this procedure.

Explanation:

I hope this helps :)

A gene pool is defined as the number of alleles. and the allele frequency is defined as the  genes that appear in a population. Therefore, option B is correct.

What is gene pool ?

A gene pool is the collection of all the genes (including alleles) found in a population or species that is capable of reproduction. A big gene pool has a wide range of genetic diversity and is more resilient to environmental stresses.

A gene pool is the collection of all the genes, including all the various alleles, in any population that mates with other individuals from the same or different species. The percentage of an allele within a population is known as the allele frequency.

A population's gene pool will include a high number of genes with a wide range of frequencies. Gene frequencies are proportions of various alleles within a population, and in any given generation, these frequencies will rely on those of the previous generation.

Thus, option B is correct.

Polina was waiting for her mother, Bearnice, to return hwith some tasty seal blubber for lunch. Bearnice was hunting, waiting for seals to come up for air through holes in the ice, the same way Polar Bears have hunted in the winter for centuries. Except this year there was one big difference.A lot more of the ice had melted last summer, and this winter it hadnt refrozen as usual. A combination of warmer weather and changes in water and air currents was making the ocean warmer than anyone could remember, and Bearnice had to swim farther every day to find a good hunting spot.As Polina waited for her mother to bring food back to her floe, the ice shrank bit by bit until she was sitting on very thin ice. As Polina waited helplessly, the furry white cub heard a deep voice coming from the direction of the sea.Hellooo little bear, it said. Polina had never heard such a deep voice. She lifted her tired head to look out over the water, and was surprised that the voice seemed to come from a dark ice floe just offshore."No, wait!" It had a huge eyeball that was looking directly at her. It wasnt an ice floe it was the largest whale Polina had ever seen. It was also the first whale that had ever spoken to her.They call me Farswimmer,said the whale, because I travel all over the world, having adventures and learning new things. What brings you here alone, Polar Bear? Farswimmer was very old, and he had seen many changes in his years of exploring the oceans. He certainly knew more about the world than most polar bears. Farswimmer seemed like a nice whale, but Polina remembered Bearnice, her mother, and how she hadnt come back from hunting.Farswimmer blew a tall spout to distract Polina and stop her from crying.When Polina told the whale her own story, he said, Im headed north anyway. You could ride on my back, and we can look for your mother. Are you ready for an adventure? The next morning, Farswimmer and Polina charted their course and took off. Polina rode Farswimmers back and sometimes floated behind him, holding his tail. She also stood on his back and pretended she was surfing. It was a blast.They took a break on an ice floe. Soon, they saw something in the distance that looked like another ice floe, but just to be sure, Farswimmer left Polina on the ice and swam to the floating object.It wasnt an object. It was an animal. Farswimmer used his fat nose to push the animal to Polinas icy raft. When they got closer, Polina saw a familiar face.Mommy, she yelped.

She opened her arms and the two embraced each other in a big bear hug.Read the passage on the left to answer the following questions:1) What is the main conflict in this story?A) Farswimmer cannot find Polina's mother.
