1. The <span>conclusion that can be made about the results of your first cross between a homozygous red bull (RR) and a heterozygous red cow (Rr) is shown below : 
You supposed to make a punnet square, so (picture)
</span>Than you will get that the first generation will be 50% homozygous dominant
and 50% heterozygous which lead us to conclusion :
<span>Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote). 
</span>
2. Conclusion about the results of your second cross between a heterozygous red bull (Rr) and a heterozygous red cow (Rr) is shown in the second picture. And you can see that <span>in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive).

3. Conclusion about </span>the results of your third cross between a homozygous white bull (rr) and a homozygous white cow (rr) are shown in the third picture. In this case you can see the result of <span> 100% (homozygous recessive).</span>

With adequate hydration, what is the expected approximate, normal daily urine production of an adult?
kicyunya [14]

Answer:

With sufficient hydration of about 2liters daily, the normal urine volume expected of an adult is between 800-2000 milliliters

Explanation:

The normal range of fluid required by an adult is 2 liters daily. Urine is produced by the kidney and it account for the largest volume of water leaving the body.

The kidneys adjust the volume of urine ejected based on the body's water requirements; if the body is dehydrated, less urine is ejected and if there is sufficient or excessive hydration, more water is excreted as urine.

Which is NOT an immune component that can directly attack &amp; destroy target cells?
lara31 [8.8K]

Answer:

Macrophages are part of your innate immune system, which is antigen-independent and does not require activation.

Explanation:

Macrophages phagocytize (internalize) all non-self pathogens it encounters. These do their job without activation. Other cells in the innate immune system include basophils, neutrophils, eosinophils (these cells are polymorphonuclear leukocytes), mast cells, and dendritic cells, which act as the bridge between your innate and adaptive immune system.

All of the other entities listed above are part of your adaptive immune system. The adaptive immune system is antigen-dependent and requires activation. This section of your immune system responds differently to different pathogens, and has the bonus of having immunologic memory, the ability to remember pathogens after infection and respond much quicker upon secondary and tertiary encounters.

Note: All lymphocyte types begin as naïve cells, which then differentiate into their fully matured form upon activation.

Helper T cells are a type of CD4+ T cell that has the job of activating B and T lymphocytes. There are two different types of T helper cells: Th1 and Th2. Th1 cells secrete the cytokine interferon-gamma (IFNγ), and is primarily involved with the stimulation and activation of cytotoxic T cells, while Th2 cells secrete a variety of cytokines and are responsible for activating and assisting with B cells to make antibodies. To make a long story short, Th cells interact with APC (Antigen Presenting Cells), specifically their Class II MHC (a group of genes that present exogenous proteins). The Th cells then proliferate and gain the ability to activate these APC cells and provide the necessary signals to activate B and T cells and make them proliferate and do their specific function.
