Explain why polar and ionic R groups are hydrophilic.

Answers

Answer 1

Explanation:

They are hydrophobic. About 5 amino acids have polar side chains, R-groups which do not ionize or become positively or negatively charged. These R-groups are neither strongly hydrophilic nor hydrophobic. Atoms in long molecules, such as polypeptides, are not rigidly fixed in space or position

1)density dependent limiting factor
2)density independent limiting factor
3)immigration
4)emmigration

Answers

Answer:

The correct answer is - 2) density-independent limiting factor.

Explanation:

Density-independent limiting factors are the factors that cause a change in the size of the population without getting influenced by the density of the population.

Density-independent limiting factors include biotic or abiotic factors with catastrophic conditions such as natural disasters such as floods, earthquakes, drought, fires, and many more.

Drought affects the size of the population by increasing competition in the ecosystem for resources.

Explanation:

cytokensis is the physical process of cell division. It divides the cytoplasm of a parental cell into two different daughter cells.

In plants, a cell wall forms. Cytokensis occurs in mitosis and meiosis. The objective for cytokensis is to divide the parent cell into two daughter cells. So cytokensis in plants is when a cell wall forms in between the daughter cells. Plant cells have walls, so they CANNOT divide using a cleavage furrow. A cell plate forms across the cell during telophase.

In animal cells, cleavage furrow forms. This pinches the cell in half and forms two different cells.

Explain the effects of air pollution on several European countries. (Site 1)

Answers

Answer:

Air pollution harms human health and the environment. In Europe, emissions of many air pollutants have decreased substantially over the past decades, resulting in improved air quality across the region. However, air pollutant concentrations are still too high, and air quality problems persist. A significant proportion of Europe’s population live in areas, especially cities, where exceedances of air quality standards occur: ozone, nitrogen dioxide and particulate matter (PM) pollution pose serious health risks. Several countries have exceeded one or more of their 2010 emission limits for four important air pollutants. Reducing air pollution therefore remains important.

Air pollution is a local, pan-European and hemispheric issue. Air pollutants released in one country may be transported in the atmosphere, contributing to or resulting in poor air quality elsewhere.

Particulate matter, nitrogen dioxide and ground-level ozone, are now generally recognised as the three pollutants that most significantly affect human health. Long-term and peak exposures to these pollutants range in severity of impact, from impairing the respiratory system to premature death. Around 90 % of city dwellers in Europe are exposed to pollutants at concentrations higher than the air quality levels deemed harmful to health. For example, fine particulate matter (PM2.5) in air has been estimated to reduce life expectancy in the EU by more than eight months. Benzo(a)pyrene is a carcinogenic pollutant of increasing concern, with concentrations being above the threshold set to protect human health in several urban areas, especially in central and eastern Europe.

"Air pollution is causing damage to human health and ecosystems. Large parts of the population do not live in a healthy environment, according to current standards. To get on to a sustainable path, Europe will have to be ambitious and go beyond current legislation."

What is the variety of gene combinations that exist within a population called?

Answers

Population geneticists study the variation that naturally occurs among the genes within a population. The collection of all the genes and the various alternate or allelic forms of those genes within a population is called its gene pool.

A population's genetic diversity can be quantified via genetic variation, genetic diversity is the term used to describe the genetic variation of an entire species.

What is genetic variation?

Each variant of a gene is referred to as an allele, and genetic variations are the variances in DNA segments or genes across individuals.

A population's naturally occurring genetic diversity is studied by population geneticists. A population's gene pool is made up of all the genes and different alternative or allelic versions of those genes.

Some genes exist in a number of forms, all of which share the same genetic locus on a chromosome.

Therefore, genetic diversity is the variety of gene combinations that exist within a population.

At the end of their biology unit, 7th grade students were asked to make a glossary of biological terms. Which student did the best job of defining the word "heredity"?​

A) Kendall- Heredity is the study of chromosomes and the genes that they contain.

B) Carla- Heredity is the passing of genetic information contained in chromosomes from one generation to the next.

C) Joseph- Heredity is the study of human characteristics passed down from parent to offspring.

D) Devon- Heredity is the reason that tall parents will usually have tall children.

Answer:

The correct answer is:

Carla- Heredity is the passing of genetic information contained in chromosomes from one generation to the next. (B)

Explanation:

Heredity, also known as inheritance is the passing down of genetic traits and genetic information from parents to their offspring through reproduction (sexual or asexual), and this information is contained in DNA materials called chromosomes.

Carla's definition most appropriatly captures the context of genetics, while Kendall and Joseph rather defined "genetics", which is the study of heredity.

Devon did not give a definition, but rather an example.

Athletes train at high altitude, thereby increasing the number of red blood cells, to improve their
performance. How might an increase in the number of red blood cells improve an athletes
performance?​

Answers

Answer:

Preparing at moderate height may improve ocean level execution in perseverance competitors. This was noted after the 1968 Olympics in Mexico City (7600 feet) when a few competitors found an improvement in their presentation after re-visitation of ocean level. Be that as it may, different competitors didn't see any distinction in execution. Studies have indicated improved high-impact power in sprinters who prepared at 6,000 feet for 10 days at that point performed at low elevation. Lower oxygen levels at elevation invigorate EPO prompting expanded red platelets or hematocrit. This viably permits more oxygen to be conveyed to the tissues. Basically, this is blood doping the regular way.  

Late examinations do propose profits by 'preparing low' and 'dozing high'. This incorporates hypoxic tents that numerous competitors are presently utilizing. These tents have a generator that extricates oxygen from the air, establishing a moderate height climate. Competitors at that point rest/relax in them for a few hours per day. This invigorates erythropoietin, subsequently expanding the hematocrit (red platelet tally). Without a doubt the 'live high, train low' idea may permit the best blend. One examination separated 39 contenders into three preparing gatherings; living and preparing adrift level, living at height and preparing adrift level, living at elevation and preparing at height. The two gatherings who inhabited height had expanded red platelets and VO2max, however just the gathering who lived high and prepared adrift level had improved race times. One clarification for this is that the live high, train low gathering can prepare more diligently and better use their blood's oxygen conveying limit. As a result of expanded red cell creation, all competitors preparing as well as resting at elevation should ensure they have proper iron stores and nourishment. This is particularly valid for ladies, as they will in general have lower iron stores because of occasional loss of blood through monthly cycle.

How could plants living in an industrial area be affected by smog?

Answers

Answer: The ground level ozone present in the smog also inhibits plant growth and causes immense damage to crops and forests. ... The smog results in mortifying impacts on the environment by killing innumerable animal species and green life as these take time to adapt to breathing and surviving in such toxic environments.

Explanation:

A type of air pollution in which the fog and smoke get mixed in the atmospheric air is called smog. It causes opacity and odour in the environment.

Smog is released from the factory that contains carbon dioxide, sulfur dioxide and smoke from the outlets.

Smog blocks the sunlight and the chemical released goes into the root system of plants interfering with the plant metabolic processes.

This causes damages to the leaves of plants and inhibits the plant process.

Therefore, smog from industries kills the plant.
