Answer:

systolic - pumping, diastolic - relaxed

Explanation:

the period of contraction is called systole, and the period of relaxation is diastole. when measured, your systolic pressure is when the heart is pumping, and diastolic is in between beats when the heart relaxes. hope this helps :)

6. what is the approximate weight in kd of the band that is unique to crab muscle protein and is not found in abundance in fish?

xenn [34]

75Kda is the approximate weight of the band that is unique to crab muscle protein and is not found in abundance in fish.

An incredibly complex, naturally occurring molecule known as a protein is made up of amino acid residues connected by peptide bonds. All living things contain proteins, which are the building blocks of numerous vital biological substances like enzymes, hormones, and antibodies.

Lack of protein can result in muscle mass loss, which reduces strength, makes it more difficult to maintain balance, and slows metabolism. When your cells don't receive enough oxygen, it can also cause anemia, which makes you exhausted.

While an excess of amino acids is often eliminated, an excess of protein is typically retained as fat. Over time, this may result in weight gain, especially if you try to boost your protein consumption while consuming too many calories.

Meiosis Foldable Activity 515.2

Aleksandr-060686 [28]

Explanation:

During the process of prophase I, the nuclear envelope containing chromosomes has only partly broken down homologous chromosomes are joined together by proteins and a complex or pairing call synapsis- corresponding genes on sister chromatids are aligned precisely.

The syanapsis allows for crossing over which is the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. In meiosis, the number of chromosomes (2n) is halved to 23 chromosomes (haploid number)through meiotic divisions, producing 4 haploid (n) germ cells or gametes (sperm or eggs), each containing half the number of chromosomes as its parent cell.

In Meiosis I

homologs pair off into bivalents
At crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined in prophase I forming bivalents; tetrads are formed.
Spindle fibers from centrioles join sister chromatids together at their centromeres in metaphase I, pulling them to the equator of the cell;
then, in anaphase I, while joined, they are pulled to opposite sides of the cell; the cell body splits and the nuclear envelope reforms in telophase I

In Meiosis II...

Later, in prophase II, the nuclear envelope disintegrates and mitotic spindle fibers are formed
independent assortment occurs. in metaphase II of meiosis: spindle fibers attach to centromeres, chromatids align independently at the equator. Genes segregate independently into new combinations as sister chromatids are pulled apart by their centromeres in anaphase II
in telophase II the cells' nuclei and membrane are then formed with each containing the haploid number (n)
Following the formation of gametes in the last stage, randomized fertilization occurs in sexual reproduction sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

Which term refers to a group of organisms that are known to be discontinuous with each other?

hammer [34]

The Term is called Niche Full distance of physical and biological setting in which an organism lives and the way in which the organisms uses those conditions. Causing species to divide resources, competition helps determine the number and kinds of species in a community and the niche eacthcies occupies.
