frutty [35]3 years ago
4 0

Answer:

Explanation:

First-generation (F1) progeny only showed the dominant traits, but recessive traits reappeared in the self-pollinated second-generation (F2) plants in a 3:1 ratio of dominant to recessive traits. Mendel then crossed these pure-breeding lines of plants and recorded the traits of the hybrid progeny

____ [38]

Answer:

(C). white blood cell production

Explanation:

CSFs (colony stimulating factors) are glycoproteins that activate intracelluar pathways and promote proliferation of hemopoietic stem cell to form immune cells (white blood cells).

CSFs are released in response to infection and interacts with blood stem cells to produce new immune cells. These resulting new immune cells create an army of cells to fight against the infection and provide immunity.

Thus, the correct answer is option (C).

Ryan wants to see if storing his batteries in the refrigerator will make them last longer. He goes to Target and buys four batte
bulgar [2K]
<span>The battery which Ryan kept in fridge, assuming it was well protected from any moisture or water, it would tend to play the CD longer than the one stored in a desk drawer. This is because storing batteries in a cool dry location while protected from any moisture or water, can help to prolong shelf life. This is due to the fact that low temperatures tends to slow down the electric current flow within the electrolyte fluid inside the battery, hence, the rate of power dissipation is reduced thus slowing down of the power drain from battery by the electric current flow . Thus, the battery stored in the fridge tends to have lost less power, if any, compared to the one stored in a desk drawer.</span>

Refer to Animation: Countercurrent Multiplication. What would you predict to be the effect on an animal species of having longer
attashe74 [19]

Answer:

The correct answers is: I would predict that animals with longer loops of Henle would be able to concentrate their urine more than animals with shorter loops, and thus they would more likely survive in desserts and other dry areas.

Explanation:

The<em> Loop of Henle</em> is a tubule system that connects the proximal convoluted tubule to the distal convoluted tubule in a nephron, the functional and structural unit of the kidney. Its primary job is to establish a concentration gradient in the kidney's medulla by creating a high urea concentration deep in the medulla using a countercurrent multiplier system that uses electrolyte pumps. Through this mechanism, <u><em>water is reabsorbed to concentrate the urine and impede dehydration</em></u>.

The length of the loops of Henle is of great importance for the countercurrent multiplier system - <u>the longer they are, the more concentrated the urine can get</u>. Therefore, animals with longer loops can survive better in habitats where there is not much water around.

The process of DNA replication occurs just before ______________.
bazaltina [42]
I believe your answer would be "Cell division"
DNA replication occurs just before the process of cell division which is also known as mitosis.

Mitosis is when the cell is being divided into two and this is when DNA starts to replicate and it produces more cells and the process goes on and on and no. 

Hope this helps. c:
