The traits for blood type and Rh are the result of the presence or absence of particular on the erythrocytes.g

Answer: Antigens

Explanation: The ABO system of blood grouping is based on the basis of the type of antigens that are present in the red blood cells. Erythrocytes is another name for the red blood cells. Antigens are molecules that are capable of eliciting immune response. There are two types of antigens: antigen A and B. Blood type A has only antigen A, blood type B has only antigen B, blood type AB has both antigen A and B while blood type O has no antigen (neither A nor B antigen).

Similarly, Rh trait is determined by the presence or absence of rhesus antigen in the erythrocytes. Rhesus antigen is an antigen first discovered in rhesus monkey. Rh+ indicates the presence of rhesus antigen in the red blood cells while Rh- indicates the absence of rhesus antigen in the red blood cells.

What were two consequences of the French and Indian War? Include the Proclamation
34kurt

Answer:

1. The French and Indian War began in 1754 and ended with the Treaty of Paris in 1763. The war provided Great Britain enormous territorial gains in North America, but disputes over subsequent frontier policy and paying the war's expenses led to colonial discontent, and ultimately to the American revolution.

2. In the long-term, the Revolution would also have significant effects on the lives of slaves and free blacks as well as the institution of slavery itself. It also affected Native Americans by opening up western settlement and creating governments hostile to their territorial claims.

Capsular hydrostatic pressure is the chief force pushing water and solutes out of the blood and across the filtration membrane.
frozen [14]

Answer:

False

Explanation:

Capsular hydrostatic pressure is not the main force that pushes water and solutes out of the blood and through the filtration membrane.  On the contrary, this pressure acts against the filtration membrane, making it difficult for water and solutes to escape from the blood.

Increasing this pressure decreases the infiltration rate and causes obstruction of the urinary tract that tends to accumulate urine, causing a lot of pain to the patient with  Renal Failure.

Scientists use DNA sequencing to understand relationships among life on Earth. The chart illustrates differences between five sp
OlgaM077 [116]

Answer:

With respect to the differences in the DNA sequence of six species, including the human one, it is true that the DNA sequences may vary but the aminoacid sequences are identical.

Explanation:

Options for this question:

  • <em>The DNA sequences may vary but the amino acid sequences are identical. </em>
  • The nitrogen bases in the nucleotides must also be different in each.
  • The process in producing additional DNA, replication, is identical in all six.
  • The process of producing DNA, or replication, varies due to the differences in the DNA codes.

The different species that exist have specific genomes for each of them, this is the <u>genetic information contained in the DNA varies from one species to another</u>, as can be seen in the scheme (see image). However, the genetic code is universal, and does not vary from one species to another.

The genetic code is found in the RNA molecule and is a sequence of nucleotides that, organized in triplets (codons), are responsible for the synthesis of specific amino acids. An RNA molecule contains the information necessary for protein synthesis.

The scheme shows the differences of five species with respect to the human, based on the respective DNA sequences. But what it does not show is a universally accepted truth, that the nucleotide sequence encoding an amino acid is the same for each of these species.

Tendon sheaths ________. Tendon sheaths ________. are lined with dense irregular connective tissue help anchor the tendon to the
leonid [27]

Answer:

Tendon sheaths <u>act as friction-reducing structures.</u>

Explanation:

Tendon sheaths are fibrous tissue that is around tendons to protect and make the movements of these smoother. For example, they reduce the friction of the flexors and extensors tendons of the hand. These are tendons that we constantly use to open and close our hands when we want to grab objects. Without the sheath, the tendons will not move easily, and due to the excessive use, there can be inflammation.

The sheats have two layers, one internal, which is a synovial one that produces synovial fluid to lubricate the tendon, and the external, which is a fibrous layer.
