bezimeni [28]3 years ago
4 0
Cephalization describes the process by which organisms develop a distinct head. The head of a cephalized organism contains a concentrated group of nerves, or brain, that controls the rest of the organism, as well as specialized organs for consumption and perception, like mouths, eyes and ears. Cephalized organisms exhibit a distinct division between parts of the body; they have a front, back, top and bottom. These animals comprise the bulk of animals that are encountered on a daily basis.

Reabsorption of filtered glucose from the lumen in the pct is largely by means of:______.
Alika [10]

Reabsorption of filtered glucose from the lumen in the pct is largely by means of: secondary active cotransport.

Nephron is the functional unit of the kidney associated with removing waste products from the blood. It achieves the function by performing filtration which results in formation of urine. A nephron is divided into two parts namely renal corpuscle and renal tubule. Renal corpuscle is associated with filtration and renal tubule mainly performs reabsorption.

Renal tubules are further divided into Proximal Convoluted Tubule (PCT), loop of Henle, Distal Convoluted Tubule (DCT) and collecting duct. PCT and DCT are mainly linked with reabsorption and secretion respectively. Reabsorption in PCT occurs via cotransport. Here, glucose is reabsorbed along with sodium ions via SGLT2 cotransporter. Specifically, the reabsorption method is termed as sodium-coupled secondary active transport.

Jorge is drawing an atomic model. The part of the atom that he has drawn is shown below. What does Jorge need to add to complete
Kitty [74]

Answer:

An atom is the smallest particle in a chemical element that holds its chemical properties. Although in the past it was thought impossible to break an atom, within modern chemistry we know that an atom is composed of subatomic particles, which compose the atomic model:

1) electrons, which have a negative charge, such a small size that it is immeasurable, and a mass much smaller than the other two subatomic particles; 2) protons, which have a positive charge; and 3) neutrons, which have no charge.

The protons and neutrons form a dense and massive atomic nucleus, which is called multipons nuclei. The electrons form a cloud of electrons that surround the nucleus.

How many sperm cells are created from the process of meiosis
Lorico [155]
While mitosis produces 2 daughter cells from each parent cell, meiosis results in 4 sex cells, or gametes in males and 1 in females. Unlike the cells created by mitosis, gametes are not identical to the parent cells. In males, meiosis is referred to as spermatogenesis because sperm cells are produced.

I need a thesis statement about whether or not transgender women should be allowed to compete in biological females sports. Plea
ELEN [110]
Thesis statement: People view transgender people as if they have an advantage when it comes to sports. Transgender women should be aloud to join a biological female sport because at the end of the day they are a female and we have to accept that.

this is you’re own opinion so i can’t really tell you what to exactly write, just write what you think and you’ll be okay.
