Answer:
You can only hunt dear (example) for only sertin times of the year because when the doe's have their fans people want them to get big before they shoot them
Answer:
Animal populations can change from one season to another, so it’s important to restrict hunting to seasons when the population is high. Such a restriction helps prevent a severe drop in population, which could threaten the species. It’s also important to limit hunting during breeding seasons to increase the possibility of offspring reaching adulthood.
Explanation:
Plato.
The poles experience 6 months of daylight and 6 month of darnos . The sun is never higher than 23.5 degrees above the horizon . Use one or both of these ideas as evidence to explain why the season are most extreme at the poles
Answer:
North and South pole are cold as they do not receive direct sunlight. South pole is much colder than North pole. The Sun is always low on the horizon, even during summer and winters.
The Sun only comes up for a few months, that is why both nights and days are dark and cold.
The average mean temperature in summers at North pole is 32 degrees Fahrenheit and in winters its minus 40 degrees. While at south pole it is minus 18 degrees Fahrenheit and in winters it is minus 76 degrees Fahrenheit.

When you examine fluid that you have drawn from a blood vessel in someone's arm, you find that it is relatively high in carbon dioxide and waste products. Assuming that the fluid comes from a healthy individual, you conclude that the blood vessel from which you have drawn blood could have been ______.
Answer:
The given blank can be filled with a venule.
Explanation:
A small blood vessel in the microcirculation, which connects the capillary beds to the veins is known as the venules. Various venules combine to form a vein. The walls of a venule are formed of three layers, that is, the inner endothelium formed of squamous endothelial cells, a middle layer of elastic and muscle tissue, and an external layer formed of fibrous connective tissue.
The size of a venule ranges from 8 to 100 micrometers in diameter and are produced when capillaries come in close association. A venule refers to a small blood vessel that permits the deoxygenated blood high in carbon dioxide and waste products to return from capillary beds to the bigger blood vessels known as veins.

When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals may form. How is this possible? When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals may form. How is this possible? Two diverged populations are capable of mating and producing viable and fertile offspring. Hybrid individuals may have reduced fitness and thus be strongly selected against. Hybrid individuals are always allopolyploid and are thus unable to mate with either of the original species. One species has a selective advantage, so as hybridization continues, the other species will go extinct.
Answer:
Two diverged populations are capable of mating and producing viable and fertile offspring.
Explanation:
Although the biological concept of species says that two different species can not mate and produce viable fertile descendants, the hybrid zones are characterized for being an area where two different genetically groups meet and reproduce. These groups might be the same or different species.
This is a frequent phenomenon in nature, and widely common geographically and among taxonomic groups. It is not rear that different sympatric populations, with a short time of divergence and similar reproductive strategies, can hybridize and even generate new populations that get reproductively isolated from their parentals.
When talking about sympatry we refer to two similar species that coincide in part or their whole distribution area.
These new populations are even morphologically different from the parental forms, which allow them to colonize new habitats and niches, promoting diversification.
Hibridation zones are very important to conserve, just because they are points of genetic diversity generation and diversification areas.
When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals can form. This is possible because hybrid individuals are always allopolyploid and therefore are unable to mate with any of the original species, to understand more we need to know that......
Hybrid animalsHybridization, that is, the process through which different species reproduce, generating an offspring, is not considered a very common phenomenon in nature. This is because, in general, species have a distinct number of chromosomes, the cell structures that contain genes. These differences in the number of chromosomes can make the development of the embryo unfeasible, as the alignment of equivalent chromosomes from the female and the male are necessary for the division of the fertilized cell to occur. When this alignment does not occur, the cell does not reproduce and dies. However, in some cases, even with the lack of chromosome pairs, reproduction between different species is successful, generating the hybrid. However, the birth of the individual does not mean that its survival is guaranteed. Often, the hybrid generated is weaker than its parents and does not survive; in other cases, the hybrid can adapt better to the environment than the species that conceived it.
With this information, we can conclude that hybrid animals are a cross between two different species, but this hybrid can have several complications for its survival.

If the number of cigarettes smoked increases, then the risk for lung cancer increases. Independent variable: _______ Dependent variable: _______ If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase. Independent variable: _______ Dependent variable: _______ If the amount of milk a person drinks increases, the strength of his or her bones will stay the same. Independent variable: _______ Dependent variable: _______
Complete Question:
Part A: Identifying Variables
Read the following hypotheses and identify the variables.
If the number of cigarettes smoked increases, then the risk for lung cancer increases.
Independent variable: _______
Dependent variable: _______
If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase.
Independent variable: _______
Dependent variable: _______
If the amount of milk a person drinks increases, the strength of his or her bones will stay the same.
Independent variable: _______
Dependent variable: _______
Answer/Explanation:
Dependent variables are variables that is dependent on the independent variables. That is, it is the variable that changes as the independent variable changes.
Depedent variable is the main interest if a researcher. It is the variable that is measured in a research work.
In the above given hypotheses, the dependent and independent variables are shown below:
1. "risk for lung cancer" is dependent on the "number of cigarettes smoked".
"Risk for lung cancer" => dependent variable
Number of cigarettes => independent variable
2. "number of shark attacks on humans" is dependent on "number of sharks swimming".
Dependent variable => number of shark attacks on humans
Independent variable => number of sharks swimming
3. Dependent variable => strength of bone
Independent variable => amount of milk a person drinks
Answer:
Lab: Heart Rate
Part A: Identifying Variables
The dependent variable happens as a result of values/changes associated with the independent variable.
Independent variable: number of cigarettes smoked
Dependent variable: risk for lung cancer
Independent variable: number of sharks swimming in a coastal region
Dependent variable: number of shark attacks on humans
Independent variable: amount of milk a person drinks
Dependent variable: the strength of his or her bones
Part B: Heart Rate
Hypothesis: If I hold my breath for 30 seconds, then my heart rate will
(choose 1) increase/decrease.
Independent variable: holding my breath
Dependent variable: heart rate
Part C:
The heart rate decreases because oxygen exchange in the lungs decreases.
This depends on what you chose for heart rate in the hypothesis. If you said the heart rate decreases after holding your breath, and the results showed the heart rate decreased, then the hypothesis is supported. If you said the heart rate decreases after holding your breath, and the results showed the heart rate increased, then you refuted the hypothesis.
Heart rate can change due to an increase or decrease in activity, moving positions such as sitting and standing, and emotions.
Example: Increase in activity—jumping jacks
Hypothesis: If I do five jumping jacks, then my heart rate will increase.
Test hypothesis. You can use the average resting heart rate from the previous experiment. If you do an experiment with an increase in physical activity like jumping jacks, then your data will reflect an increase in heart rate because the body requires more energy, which requires more oxygen, increasing the overall flow of blood in the body.
Support or refute the hypothesis based on the results. The hypothesis is supported if it aligns with the observed results. The hypothesis is refuted if the results don’t match the statement based on the variables.
Testing more than one variable at a time makes it difficult to interpret the results and support or refute the hypothesis. With one variable, the results can be associated with changes to that variable. To get the most reliable data to support or refute a hypothesis, an experiment should be completed several times to see if the results show the same trends.

Bile juice dose not contain any digestive enzymes yet it is essential for digestion why so ?explain
Explanation:
Although bile juice does not contain any enzymes, it contains bilirubin and biliverdin. These help to break big fat globules into small globules which is taken to pancreatic juices to be further digested. This is known as emulsification of fat. It also helps in secretion of lipase. Thus it plays an important role because majority of the fat digestion process is carried out by it.

Answer:
Temporal isolation
Explanation:
Temporal isolation, a type of reproductive barrier caused by variations in the timing of mating receptivity, activity, or fertility, prohibits interbreeding between different but closely related species.
What is the temporal barrier in reproductive isolation?In biology, temporal isolation is a form of reproductive isolation mechanism that prevents members of closely related species from mating and creating hybrid offspring.
Temporal isolation refers to the situation where two or more species reproduce at various periods. For instance, three different types of orchids live in the same rain forest.
This mechanism arises from differences in the timing of crucial reproductive events.
Therefore, Temporal isolation reproductive barrier will most likely be working against that possibility.

A. understand the viewpoint of other people.
B. realize that the term heavy describes an object one way and the term big describes it another way
C. understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.
The answer is C
Explanation:
Piaget proposed the theory of cognitive development, which talks about how human intelligence is developed. Piaget worked with Children because he believed they played a significant role in the development of cognitive intelligence. Based on his work, he proposed four stages of cognitive development viz: sensorimotor, preoperational, concrete operational and formal operational stages.
However, in the preoperational stage, Piaget described children between ages 2-7 as being in this stage of cognitive development where they are yet to comprehend mental logic. One characteristics of this stage is CONSERVATION, which is the ability to know that changing a substance's appearance doesn't change the properties of that substance. Piaget proposed that Children between the ages of 2-7 lacked this conservative characteristics.
He performed an experiment where he used two beakers with the same amount of liquid. He then emptied the contents of one of the previous beakers into a new beaker with different shape (longer). Piaget was able to notice that Children at the pre-operational stage were unable to understand that the contents of the two beakers (longer one and previous beaker) were still the same despite the beaker has been changed.
Hence, according to Piaget, a child has acquired the cognitive skill of conservation when he/she is able to understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.

TLRs are Group of answer choices the coatings of pathogens by complement. present in intact skin, sebum, tears, etc. phagocyte receptors that detect PAMPs. nonspecific leukocytes that secrete toxins onto the surface of virally infected cells. molecules that damage cells, resulting in cell lysis.
Answer: Phagocyte receptors that detect PAMPs
Explanation:
TLRs or Toll-like receptors, are a family of proteins that are part of the innate immune system. TLRs are transmembranous and recognize pathogen-associated molecular patterns (PAMPs), which are groups of chemical characteristics common to certain types of pathogens. Patterns detected by TLRs include lipopolysaccharide, a compound found on the surfaces of Gram-negative bacteria, and double-stranded RNA, which is an integral part of the life cycles of many viruses. These PAMPs are generally important for the survival of the pathogen, so they are well preserved. Activation of these receptors induces inflammatory responses in leukocytes of myeloid lineage, signaling via NF-κB, which is a transcription factor that activates pro-inflammatory genes. Activated TLRs also increase the production of co-stimulatory molecules such as CD80, CD86 and CD40. These proteins, expressed on the surface of antigen-presenting cells, are necessary for the activation of T-lymphocytes by dentritic cells and macrophages already showing antigens in their MHC type II molecules (Major Histocompatibility Complex, they participate in the presentation of antigens to T lymphocytes)
In addition, TLR-mediated signaling on antigen-presenting cells (APCs) plays an important role in linking the innate and adaptive immune responses.

Fungus to Hawk toRattlesnake to Kangaroo Rat to Cactus C. Cactus to Kangaroo Rat to Rattlesnake to Hawk to Fungus D. Cactus to Fungus to Kangaroo Rat to Hawk to Rattlesnake
ANSWER:
C. Cactus to Kangaroo Rat to Rattlesnake to Hawk to Fungus
EXPLANATION
Living organisms in an ecosystem obtain energy by feeding on one another. As one organisms feeds on the other, ENERGY FLOWS. However, the flow of energy is UNIDIRECTIONAL. The flow of energy is represented by a FOOD CHAIN where the arrow signals which organism is feeding on which.
According to this question, a typical example of energy flow in a terrestrial ecosystem is as follows:
Cactus → Kangaroo rat → Rattlesnake → Hawk → Fungus
In the above food chain, energy flows as cactus plant (producer) is fed on by kangaroo rat (primary consumer), which is fed on by rattlesnake (secondary consumer), which is fed on by hawk (tertiary consumer). Hawk is decomposed by fungi (decomposer) when it dies. Energy flows in this direction.
Hence, an example of the way energy flows in an ecosystem is represented by Cactus to Kangaroo Rat to Rattlesnake to Hawk to Fungus
