I hope its help you Thank youA researcher is studying three wolf packs that hunt in the same area. The first pack preferentially kills mature, healthy moose; the second pack preferentially kills sick, old moose; and the third pack tends to kill an equal number of healthy and sick moose. Which pack likely plays the greatest role in determining the birth rate of the moose population
Answer:
The correct answer is - the pack that preferentially kills mature, healthy moose.
Explanation:
The birth rate is the number of individuals born in a population in a particular amount of time period. The birth rate can be determined by the individual born in a particular time period and that depends on how many healthy and viable individuals in a population can reproduce and produce new individuals.
Old and sicks are not the ones who can actively participate in reproduction and, however, if the number of healthy and mature individuals are killed there would be fewer newborns in the population.
Thus, the correct answer is the pack that preferentially kills mature, healthy moose.
After Frida stops exercising, she continues to breathe heavily. What is most likely occurring in her body?
a. Heavy breathing during exercise has produced an oxygen surplus in her muscles. This oxygen is being transported to her lungs. This is a result of aerobic respiration.
b. Heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. Lactate is being transported to her liver. This is a result of aerobic respiration.
c. Strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
d. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
Answer:
D. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

The presence of a negative allosteric effector on an allosteric protein would: a. cause a shift to the left in the sigmoidal curve. b. increase the number of R conformations. c. decrease the cooperativity of the substrate. d. raise the apparent value of the equilibrium constant, L. e. increase the likelihood of the binding of S.
Answer:
d. raise the apparent value of the equilibrium constant, L.
Explanation:
Allosteric regulation is a type of regulation of an enzyme by binding an effector molecule at a site other than the protein's active site (i.e., the allosteric site). The equilibrium constant (L) refers to the transition between two forms of an allosteric protein in absence of a ligand. The properties of allosteric enzymes are explained by conformational changes associated with a low-affinity tense (T) state, or a high-affinity relaxed (R) state. Negative allosteric effectors are molecules that bind to the allosteric site on an enzyme in order to decrease its activity, thereby leading the enzyme to a low activity T state and thus increasing the value of the equilibrium constant.

Answer:
1. Syphilis
2. Gonorrhea
3. Chlamydia
4. Trichomoniasis
5. Crabs
6. Genital herpes
7. HPV
Explanation:
STD is an acronym for sexually transmitted disease and it can be defined as diseases that are easily transmissible or contractable from another person through sexual intercourse. Thus, STD spread from an infected person to an uninfected person while engaging in unprotected sexual intercourse. Some examples of STDs are gonorrhea, chlamydia, syphilis, HIV, HPV, etc.
Generally, contracting STDs has a detrimental effect to a patient because it causes an opening (break) or sore in the body of the carrier (patient) and as such making them vulnerable to diseases that are spread through bodily fluids e.g human immunodeficiency virus (HIV), Hepatitis, staphylococcus, AIDS, etc.
1. Syphilis: can cause sores, rashes, dementia, or blindness.
2. Gonorrhea: can cause burning urination and infertility
3. Chlamydia: similar to gonorrhea but more likely to be carried unknowingly
4. Trichomoniasis: parasitic STD causing genital irritation and mild discharge.
5. Crabs: pubic lice that cause itching.
6. Genital herpes: untreatable STD causing periodic outbreaks of blisters
7. HPV: can cause genital warts or cervical cancer. HPV is an abbreviation for human papillomavirus and it's a virus that causes most common sexually transmitted infection, giving rise to skin or mucous membrane growths (warts).
Answer:
1) syphilis
2) gonorrhea
3) chlamydia
4) trichomoniasis
5) crabs
6) genital herpes
7) HPV

define zygote as it is used in biology
Answer:
fertilized egg
Explanation:
Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.
Britannica
Answer:
A zygote is a eukaryotic cell that is produced when two gametes fertilize each other. The genome of a zygote is made up of the DNA from each gamete and includes all of the genetic information needed to create a new person. The zygote is the most basic developmental stage of multicellular organisms.

Using complete sentences, explain how proximity to major rivers influenced the location of early cities.
Answer:
Locations along rivers meant faster travel upstream and downstream to rule territories. The city became the place where the ruler or rulers lived together in a stationary spot. The city's location along early rivers encouraged stronger government, which in turn encouraged stronger cities.
Rivers are one of the most crucial resources that played a major role in the development in ancient times. It led to river valley civilization that influenced the location and kingdoms.
What is river valley civilization?The river valley civilization was one of the most important events that led to the establishment of many kingdoms and regions. The proximity to the river banks influenced many factors.
The cities located on the riverbanks have greater development in services including import, export, travel, agriculture, accessibility, etc. This allowed the people to practice agriculture on a large scale due to the availability of the irrigation system.
The river banks allowed the cities to grow as major trade centers and allowed downstream and upstream travel easier. This also led to the emergence of strong government systems.
Therefore, the proximity to major rivers led to river valley civilization.

The complete question with its options is:
Jenna's pencil fell off of her desk and she quickly reached down to catch it before it hit the ground. In the process, the (1)_____ system first recognized the falling pencil. It sent signals to the (2)______ system, which then moved the components of the(3) _____ system in order to catch the pencil.
Options:
(1) 1. Nervous 2. Muscular 3. Skeletal
(2) 1. Nervous 2. Muscular 3. Skeletal
(3) 1. Skeletal 2. Digestive 3. Nervous
The answer is:Jenna's pencil fell off of her desk and she quickly reached down to catch it before it hit the ground. In the process, the (1) Nervous system first recognized the falling pencil. It sent signals to the (2) Muscular system, which then moved the components of the(3) Skeletal system in order to catch the pencil.
Explanation:
The nervous system receives the signal that the pencil is falling. In other words, Jenna sees or feels that the pencil falls, so the senses send a signal to the nervous system to produce a response. We call this a stimuli. Once that the nervous system receives and processes the stimuli, it elaborates an answer. The answer is to send a signal to a group of muscles that will move certain bones to make the movement that will catch the pencil. The muscles are from the muscular system, and they are attached to the bones, which are part of the skeletal system. When the muscles contract, they move the bones and make the movement possible.
What are australopiths, how many groups are there, and what do they date to? Which one is derived and therefore not part of our direct evolutionary line?
Answer and Explanation:
Australopithecines were a group of ancestral animals that were very similar to chimpanzees, but had common characteristics with humans, which is something normal, when we think that these animals are one of the ancestors of human beings. These animals walked on two legs, like humans, but they had very small brains and teeth that were bigger and heavier than those of humans. There were eight groups of australopithecines and they date from 8 million to 1.5 million years ago.
Among these groups, it is believed that Australopithecus afarensis is a group that has no direct ancestry with humans, being a group that did not thrive during the evolutionary process.
Which group evolved first?
rays
skates
sharks
chimaeras
Answer:

Why do we shiver when it is cold?
A. It is the brain stimulating the person to move to a warmer location.
B. It is an involuntary reaction that does not actually help our body.
C. The rapid twitching of the muscles generates heat.
D. It is a side-effect of the pancreas signaling to the brain that it is losing heat.
Answer:
C. The rapid twitching of the muscles generates heat.
Explanation:
When the body detects that it is cold, it will shiver in an attempt to create heat.
The rapid loosening and tightening of the muscles in this process creates heat.
This is a involuntary and natural response that helps return the body back to homeostasis and maintain a normal temperature.
So, the correct answer is C. The rapid twitching of the muscles generates heat.
Answer:
C. The rapid twitching of the muscles generates heat.
Explanation:
When someone feels cold, tiny sensors in your skin send messages to your brain telling you that you need to warm up.
