In some animals, females select males as mates based on their ability to ward off infection as indicated by traits that the males possess. This is an example of ________.

Answers

Answer 1

In some animals, females select males as mates based on their ability to ward off infection as indicated by traits that the males possess. This is an example of honest signaling.

When females select males as mates based on their ability to ward off infection as indicated by traits that the male possess is considered signaling. Signaling theory is a corpus of theoretical work that studies communication between individuals, both within and between species, in evolutionary biology.

The key question is whether creatures with competing interests, such as those involved in sexual selection, can be expected to give honest signals instead of deceiving. Mathematical models explain how signaling might support an evolutionary approach that is stable.

Signals are delivered in situations like mate choice by females, which puts selective pressure on the signals of the advertising males. Signals change the behavior of the receiver in favor of the signaller, which causes them to develop. Signals can be honest, providing information that helps the recipient become more fit, or they might be dishonest. A person can lie by sending a deceptive signal.

Suppose you were given a chemical compound that could enter the egg and bind to Ca²⁺, blocking its function. How would you use this compound to further test the hypothesis that a rise in Ca²⁺ level triggers cortical granule fusion?

Answers

Due to the compound blocking the Ca2+ functions, their will be a delay in cortical granule fusion with the egg plasma membrane. This will test  the hypothesis that a rise in Ca²⁺ level triggers cortical granule fusion.

The cortex of unfertilized oocytes contains membrane-bound organelles called cortical granules. Cortical granules go through exocytosis after fertilization to release their contents into the perivitelline region. The cortical response is the name given to this secretory mechanism, which depends on calcium and uses a SNARE protein-mediated pathway. The cortical granule proteins that are released after exocytosis alter the extracellular matrix of the oocytes, such as the zona pellucida in mammals, to prevent polyspermy. Mammalian cortical granules, which differ from most other regulating secretory organelles in that they are not replenished once released, range in size from 0.2 um to 0.6 um in diameter. Only female germ cells may produce these granules, which change an egg upon sperm entrance.

Therefore, a delay will be observed in the cortical plasma membrane fusion.

Explain the difference between vertical and horizontal integration. How were these business models representative of monopolies?

Answers

When two firms combine, whose products and production levels are the same, then this is known as Horizontal Integration. Vertical Integration is when a firm takes over another firm or firms, that are at different stages on the same production path.

Horizontal Integration is a kind of business expansion strategy, wherein the company acquires the same business line or at the same level of the value chain so as to eliminate competition to a greater extent. Conversely, Vertical Integration is used to rule over the entire industry by covering the supply chain. It implies the integration of various entities engaged in different stages of the distribution chain.

The greatest advantage of horizontal integration is that it eliminates competition between firms, which ultimately extends the market share of the company. Conversely, Vertical Integration results in lowering the cost of production and wastage.

Horizontal Integration helps to acquire control over the market, but Vertical Integration is a strategy used for gaining control over the whole industry.

Ecological problem is one of the most important issues nowadays. Human activities have a negative impact on the environment. Humanity currently faces problems with air, water, and lands pollution, unreasonable agricultural systems, deforestation, and others. As a result, the number of available natural resources is decreasing. Another negative consequence of human activities is the process of global warming and global climate changes. These changes affect the whole Earth and might result in adverse consequences for people and wild nature

Another important action we perform to improve the situation with water is avoiding water pollution. Our family refused to use cleaning detergents with phosphates as it is known that these substances are harmful to human health. Moreover, it is difficult to eliminate these compounds from water. Therefore, phosphates in the water get to nature and poison living organisms. Thus, it is better to use detergents without phosphates. It helps to keep the healthy and to reduce water pollution

Except for water pollution, there are a lot of other problems that need to be solved. One of them is waste deposits. These deposits occupy a large area. Different wastes need different (however, always significant) times to decompose. Besides, while decomposing, a lot of harmful compounds appear. These compounds poison the land and can get to the water. In the last decades, a lot of programs of waste separation appeared. People are asked to separate the waste: to combine plastic with plastic, organic with organic, and paper with paper. Different wastes are treated in different ways, which allows cutting pollution. For example, plastic can be remolded and used again, while it requires hundreds of years for its degradation in nature. Moreover, during this process, a lot of harmful products release (Law and Thompson 144). Thus, it is better to separate plastic material and recycle it. It would be even better not to use plastic at all, and when it is possible, try to use biopolymers instead.

Answers

It would it still be preferable to introduce the drug locally because  It would make use of or take advantage of glucocorticoids' anti-inflammatory characteristics.

The effects on glucose metabolism that would occur if glucocorticoids were taken orally and circulated throughout the body are eliminated by local injections.

Although inflammation is a natural process that helps the body repair and protect itself from harm, it needs to be treated when it lasts for more than a few days or weeks. Inflammation in the joints is a symptom of arthritis.

An example of an anti-inflammatory medicine is corticosteroids. Treatment for rheumatologic conditions such lupus, vasculitis, and rheumatoid arthritis is widespread (inflammation of the veins). Explicit corticosteroids combine prednisone and cortisone.

Glucocorticoids (GCs) are frequently used to treat cancer, autoimmune conditions, and inflammation. For instance, cortisol boosts the production of glucose from non-carbohydrate sources like proteins, increasing the amount of glucose that is available for use as fuel.

When injected into the body at concentrations greater than those occurring naturally, glucocorticoids suppress some immunological components. Consequently, inflammatory disorders like arthritis are occasionally treated with glucocorticoids.

Bar graphs are used to interpret results in an experiment by comparing the change of the dependent variable under different scenarios. D) on dark-colored soil with full moonlight.

How to interprete a bar graph?

A bar graph represents the relationship between two variables, the dependent and the independent one.

Usually,

Independent variable ⇒ X axisDependent variable ⇒ Y axis

Bars represent how the dependent variables react or respond to changes in the independent variable.

These charts are used to make comparisons. This means that by looking at the different bars, the researcher can to compare how the dependent variable responds under different scenarios of the independent variable. For instance, in which situation the bar is higher or shorter.

Bar graphs turn out to be an easy and reliable way to interpret results in an experiment.

Now let us analyze this example,

The researcher compares how many mice were caught by the owl under different scerarios: different substrate color, under moonlight or not, and according to their coat color.

Coat color: white and brownSubstrate: light and darkMoonlight: Full moon - No moon

The dependent variable is the number of caught mice, which depends on coat color, moonlight, and substrate color.

The independent variables are coat color, moonlight, and substrate color. Any change in them will affect the dependent variable.

Notice that even when the researcher can not manipulate the coat color, this is also an independent variable.

The question asks under which conditions would a dark brown mouse be most likely to escape predation at night?

Well, to answer it, we just need to compare the bars height.

Higher bars means a higher number of caught miceLower bars means that mice managed to scape predation

Since the question ONLY asks about brown mice, we will limit out interpretation to brown bars.

The shortest brown bar reflects that on dark soil and under a full moon, the number of brown caught mice was the lowest, with only about 12 individuals eaten.

The highest brown bar reflects that on light soil, and under no moon, the number of brown caught mice was the highest, with about 37 animals eaten.

The bar that expresses the conditions under which brown mice managed to scape predation is the shortest one, because it tells us about the lowest number of individuals caught by the owl.

If you discovered a mutation in mice that disrupted the ability to taste sweet, bitter, and umami, but not sour or salty, what might you predict about where this mutation acts in the signaling pathways used by these receptors?

Answers

It can be presumed that the mutation is in a molecule that works in the signal transduction pathway used by all GPCRs as GPCR (G protein-coupled receptor) proteins are implicated in the sweet, bitter, and umami tastes but not the sour or salty tastes.Specialized taste receptor cells in taste buds contain taste GPCRs (TRCs). Physical similarities between sweet and umami receptors allow them to share certain agonist binding sites. Since most bitter receptors don't have a distinct binding site, different bitter ligands can attach to them.

What steps can be observed in this signaling pathway?Step 1: Taste buds come first.Specific taste buds on the tongue are involved in the perception of flavors such sweet, sour, bitter, and umami. On the tongue, there are a number of tiny sensory organs called papillae. The taste buds are found in the microscopic microvilli, which resemble small hairs and are found on the papillae.

Step 2: Taste buds' GPCR signalingGPCRs all signal the fundamental tastes, including sour, bitter, umami, and the flavor kokumi. The flavor GPCRs are located in the unique taste receptor cells of the taste buds.The sweet taste receptors are type I taste GPCRs, also known as TAS1Rs, and they have a heterodimeric structure. Monomeric bitter taste receptors are a subset of type II receptors.Step 3: Taste buds' GPCR signalingThree heterotrimeric G proteins, G-alpha Gustducin, G-beta3, and G-gamma13, couple to taste GPCRs (sweet, umami, and bitter).It starts a number of signal transduction cascades that result in IP3-dependent Ca2+ release from the endoplasmic reticulum, activation of phospholipase C-2, and synthesis of inositol-1,4,5-trisphosphate.The temporary receptors are then stimulated by the elevated intracellular calcium to potentially fire and release induced ATP, which alerts the brain to the presence of umami or other flavors.Therefore, if there is a mutation in the molecules of this signaling pathway or any other similar signaling system, the mice may lose flavors like sweet, bitter, or umami. The tastes of sour or salty won't change because they don't follow any signaling pathways.
