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.

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.

Explanation:

When activated, the receptor most likely prompting the production of saliva is the taste receptor. When food enters the mouth, the salivary glands produce the saliva upon the sensation of taste.

Answer:

Taste receptors.

Explanation:

When activated, the receptor most likely prompting the production of saliva is the taste receptor. When food enters the mouth, the salivary glands produce the saliva upon the sensation of taste. The secretion of saliva (salivation) is mediated by parasympathetic stimulation; acetylcholine is the active neurotransmitter and binds to muscarinic receptors in the glands, leading to increased salivation.

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

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.

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.

Answer: D. It provides evidence of links between evolutionary species.

Explanation: The significance to scientists of finding a new, unknown fossil is that it provides evidence of links between evolutionary species.

Organisms arose as a result of these changes, and some of their remains have been preserved as fossils. An organism's type, life history, and preservation method can all be ascertained by studying a fossil. Thus, option D is correct.

They can discover when and how various animals existed millions of years ago by studying fossils. Fossils can sometimes show scientists how the Earth has changed over time.

The discovery of a new, undiscovered fossil is significant to scientists because it shows connections between evolutionary species.

Fossils with remarkably similar geometries are thought to be from the same species. It is considered that fossils with somewhat differing geometries come from a separate species. Usually, the fossil species has been researched and given a name.

Therefore, It provides evidence of links between evolutionary species.

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.

Answer:

The correct answer is option d, that is, hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.

Explanation:

The maximum growth temperature refers to the highest temperature at which growth can take place. Let us take an example of bacteria, it is found that each bacterial species possess a requirement of specific growth temperature, which is mainly determined by the requirement of the temperature of its enzymes. Each of the organism exhibits an optimum growth temperature, a minimum growth temperature, and a maximum growth temperature.  

When for an organism, the temperature goes more than its maximum growth than it results in the dissociation of the hydrogen bonds, denaturation of the proteins, and even the membranes become too fluid. This can even result in the death of the species. However, there are some of the organisms, which can thrive high temperatures known as thermoduric organisms, but they fail to grow effectively at such temperatures.  

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.
