Describe how natural selection explains the changes in species over time .

Answers

Answer 1

English naturalist Charles Darwin discovered the idea of natural selection.

Over time, natural selection process leads to the evolution of species. This is one way to explain how millions of species have existed on Earth. For example, the long necks of giraffes give them a competitive advantage to feed on leaves over other organisms that have shorter necks.

The beneficial characteristics spread throughout the population over time. Favorable traits are transmitted through generations which results in natural selection. Natural selection can result in speciation, the process by which one species gives rise to another that is utterly distinct from it.

Which of the following is a strategy that some middle- and upper-class women have used to balance the demands of work and home? a. demanding that their husbands complete most chores b. doing more of certain chores c. hiring other women to do domestic work d. demanding the abolition of housework

Answers

Hiring other women to do domestic work is a strategy that some middle- and upper-class women have used to balance the demands of work and home.

Although women's work increases middle-class salaries, it also puts a strain on family time that needs to be alleviated.

In recent decades, middle-class incomes have only slightly increased, and the majority of those increases are due to more women finding employment and receiving greater wages. However, with the majority of women now working, that source of income growth is dwindling. Women's labour force participation has increased since the last recession, although overall growth seems to have stagnated.

Whatever gains in middle-class earnings we have seen may completely disappear in the absence of new policies and practises that involve greater sharing of the costs of unpaid work in the house, more assistance for time-constrained working families, and higher pay for both men and women. That's why they hire other women for household work.

Bears are one of the most intelligent land animals in North America. They have the largest and most complex brains compared to other land mammals their size and they rely on this brain for a number of behaviors. Bears are among the most beloved wild animals.
Bear Symbol represents strength, family, vitality courage and health. The bear is thoughtful and independent, with little need for fellowship. The bear is also self-contained and strong-willed in nature.
For example:
1/ The extinction of the grizzly bears would leave a significant impact on an ecosystem. We know that grizzle bears feed on herbivores species. So, if there are no grizzly bears, the number of herbivores species will increase and as a result number of plant species will decrease since herbivores depend on plants.

2/ When attacking humans, black bears will rear up on their hind legs and knock victims over with their paws. They then make one or two bites on an arm or leg and finish with a snap to the head, this being the most dangerous part of the attack.

briefly describe how transcription results in the production of messenger rna (mrna). what is a primary transcript?

Answers

The DNA-transcribed single-stranded RNA product known as a primary transcript is then processed to produce numerous mature RNA products like mRNAs, tRNAs, and rRNAs.

In order to be ready for translation, the primary transcripts identified as mRNAs undergo modifications. An illustration of a main transcript that undergoes processing to become a messenger RNA (mRNA) is a precursor mRNA (pre-mRNA). The creation of main transcripts involves a number of procedures. The transcription of DNA in the nucleus of eukaryotes is started and finished by a series of interactions that take place throughout all these processes.

In the activation and inhibition of transcription, where they control the creation of main transcripts, specific variables are crucial. The original transcripts created by transcription are later altered by a number of different mechanisms. The 5' cap, 3'-polyadenylation, and alternative splicing are some of these procedures. Alternative splicing in particular directly adds to the variety of mRNA found in cells. In order to understand the function and importance of these main transcripts, more research has been done on their changes.

Pheochromocytoma is a tumor that produces hormones that can develop in the adrenal glands. Typically, pheochromocytomas form in the little glands above the kidneys (adrenal glands). Although they can happen at any age, they most frequently afflict people between the ages of 20 and 50.

The adrenal medulla contains a tumor called a pheochromocytoma (the inner part of the adrenal gland). Adrenaline (epinephrine) and noradrenaline are produced by the adrenal medulla (norepinephrine). It's possible for too many of these hormones to be produced if a tumor develops in this region. Due to the extremely high blood pressure it creates, this can be highly dangerous. Although pheochromocytoma in the adrenal gland is uncommonly malignant, it may be connected to thyroid and other glandular cancers

Early diagnosis of this issue is crucial. Unsafe blood pressure may be cured by locating and treating it. If left untreated, it can result in a heart attack, stroke, and clogged arteries.

you've just had a near miss in your car. your pulse is racing and you notice your pupils are wide open when you look in your rearview mirror. what part of your autonomic nervous system is activated?

Answers

The part of the autonomic nervous system that is activated when you have a near miss in your car is the sympathetic nervous system.

The sympathetic nervous system is responsible for the activation of the “fight or flight” response. This response is triggered when the body perceives a threat, such as a near miss in a car. When the sympathetic nervous system is activated, it causes the heart rate to increase, the pupils to dilate, and other physical and mental reactions that prepare the body to either fight or run away from the perceived danger.

In the case of a near miss in a car, the body is preparing for either a fight to defend itself, or an escape from the perceived danger. This response is essential for survival and is controlled by the autonomic nervous system.

Our sympathetic nervous system also releases hormones like adrenaline and cortisol, which increase our alertness and help us focus on the task at hand. This is why we feel so tense and alert after a near miss in our car – our body is preparing us for possible danger.

The potential health risks of gene insertion are not fully understood, and this lack of knowledge has led to a great deal of fear and caution among the scientific community.

While some studies have indicated that gene insertion could have the potential to treat or cure certain diseases or illnesses, there is a lack of conclusive evidence demonstrating the safety of the process. Moreover, there is concern that gene insertion could lead to the development of new diseases or mutations, with unknown consequences.

Furthermore, the ethical implications of gene insertion are highly contested.
