1. How did the colors of each type of prey affect its population size over time?
2. What color rabbit seemed to camouflage the best in this snow habitat and why? What
color rabbit seemed to camouflage the best in the summer habitat and why?

Answers

Answer:

The more an animals color matches their surroundings, the more likely it is for survival. White rabbits fur matches the snow, and brown rabbits fur blend with the dirt

Explanation:

The colors that stand escape the many would be red and blue and the one's camouflage is mostly brown, green, and yellow, swinging on its place and surroundings.

What is the Color rabbit?

The prey that is more delicate in color lasts extended. As the duration goes on, the white prey lasts extended than the blue colors as they blend into their surroundings sufficiently.

The green, red, and orange varied practically extinct over the 3 generations because they could be stained easier and could not blend into their surroundings.

The colors were very necessary for how it influenced the people because the more brilliant the color the more predators it's going to seduce and the colors such as green and brown are more camouflage.

The more an animal's color approximates its surroundings, the more possible it is to survive. White rabbit's fur approximates the snow and brown rabbits' fur in combination with the dirt.

What is the key activating signal in the TNF receptor signaling pathway that occurs downstream of TNF-alpha binding to the extracellular domain

Answers

Answer:

TNF-alpha is expressed as a homotrimer that exerts its activities through binding to two types of receptors: TNFR1 and TNFR2, which are transmembrane glycoproteins characterized by having an extracellular domain with 4 cysteine-rich domains (CRD 1-4) , each with 3 cysteinecysteine disulfide bonds.

Explanation:

TNF-alpha (Tumor Necrosis Factor), which has the characteristic of being a paracrine signaling ligand, is a pleiotropic cytokine that functions as a mediator of immune regulation, the inflammatory response and apoptosis in some cell types. Receptors in this family are involved, with some exceptions, in juxtacrine signaling; that is, both the ligand and the receptor are membrane proteins with extracellular domains through which signaling is established. The cellular responses promoted by TNF are initiated by its interaction with two different types of cell receptors, the type I receptor (55 kDa) and the type II receptor (75 kDa). Both types of receptors are part of the TNF receptor family, members of which include Fas antigen (apoptosis inducer, also called Apo-1 or CD95), CD27 (T-cell activation antigen), CD30 (lymphoma marker Hodgkin) and CD40 (B-cell antigen), which share the characteristic of cysteine-rich sequences in their extracellular domains. This family of cytokines generate cellular responses that include differentiation, proliferation, activation of NFκB and cell death, promoting the aggregation of receptor monomers, that is, they have a transmembrane domain that participates in the solubilization of the receptor and a domain of intracellular death that is involved in signal transduction. The binding of TNF to TNF-R1 induces a signaling cascade through its intracellular death domain, which subsequently leads to the activation of complex I (or inflammatory) of NFkB and proceeds to the transcription of anti-apoptotic genes, pro- inflammatory diseases and apoptosis complex II (caspases).

why would an athlete need to be concerned about a twitch or sustained contraction​

Answers

Answer:

why an athlete would need to be concerned about twitches or contractions is because, whenever they perform, and such thing happens, it will most likely distract the athlete, and cause the athlete doing his/her performance to not be as good, and may lead to failure, for example, when someone is running very fast for a sprinting race, and he has a contraction in his leg it will cause him to react by showing signs of pain by slowing down or even tripping and falling, causing him to lose the race.

All of the following are true of spermatogenesis EXCEPT: Question 4 options: One spermatogonium produces 4 spermatids Genetically diverse spermatids are created. The products are spermatozoa that each have a head, midpiece and tail. DNA replicates once, but cells divide twice. Spermatids containing 23 chromosomes (1n) are produced.

Answers

Answer: The products are spermatozoa that each have a head, midpiece and tail.

Explanation:

The spermatogenesis can be defined as the process of gamete production in human males. It takes place in the testes in males. In this process the spermatids are produced which are four in number through reductional cell division called as meiosis. Each spermatid is haploid in number and the genetic material present in each is diverse as a result siblings are not identical to each other. The spermatozoa is an immature sperm cell which develops head, middle piece and tail. But it is not a precursor of production of sperm cells via cell division.

What's the definition of absoulute dating

Answers

Absolute dating is the process of determining an age on a specified time scale in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty and precision. Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events. In archeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates. Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped charge dating methods such as thermoluminescence dating of glazed ceramics. Coins found in excavations may have their production date written on them, or their may be written records describing the coin and when it was used, allowing the site to be associated with a particular calendar year.
