Use the words flexor and extensor to explain how muscles work in pairs.

Answers

Answer 1

By contracting, muscles pull on bones and allow the body to move. ... Each muscle in the pair works against the other to move bones at the joints of the body. The muscle that contracts to cause a joint to bend is called the flexor. The muscle that contracts to cause the joint to straighten is called the extensor

Explanation:

Given the temperatures of the areas before storm 1 and storm 2 have the same temperature 15°C and the same amount of wind blew across the areas just before the storms ( storm1 and storm 2 ) occurred.

Hence the conditions before storm 2 that could have caused more rainfall in storm 1 can be attributed to varying atmospheric conditions like; before storm 1 occurred the air parcels were most likely more warmer hence the Rainfall was higher in storm 1 but before storm 2 the air parcels moved further and lost some energy

What microbial types are likely to be present in each of your fomite samples? Of these, which are most likely to grow on the nutrient agar medium used in this investigation? Which is probably not culturable under the conditions used?

Answers

Hello. You did not enter the text to which these questions refer, which makes it impossible for them to be answered. However, I will try to help you in the best possible way.

It is only possible to answer your questions in a specific way by reading the experiment, however, I can inform you that formites are objects that allow the colonization and growth of microorganisms that can be major causes of diseases. Among these microorganisms are bacteria, fungi and viruses of the most varied species. Among these microorganisms, both fungi and non-demanding bacteria can grow in a nutrient agar culture medium. This is because this is a very simple culture medium where bacteria that do not need specific nutrients can grow and where most fungi can grow too. However, it is impossible for viruses to grow in this type of culture medium or in any culture medium, since viruses only develop inside a host's organism. Bacteria known as fastidious would also not grow in this type of culture medium, since they only grow with the presence of very specific nutrients.

And although they are large, their combine biomass is really not that big compared to some of the combined biomass of plants in those habitats. The grasslands contain scattered woody plants, but they are kept in check by the uprooting activities of the elephants. Take away the elephants, and the grasslands convert to forests or to shrublands. The newly growing forests support fewer species than the previous grasslands. What term best describes the role played by elephants in these communities

Answers

Answer:

This question lacks options, options are: a. Keystone species b. Dominant species c. Competitor species d. Omnivore species e. Mutualistic species. The correct answer is a.

Explanation:

The most connected species from a trophic point of view in an ecosystem are keystone species, since their elimination has great effects on the stability and persistence of the network. The Keystone species are those species that play a crucial role in the structure and dynamics of a certain ecosystem and that, in the event of their disappearance, would be seriously unbalanced. These species are responsible for the physical structure of the habitats of many other species, and they play an important role in the succession processes of ecosystems. Elephants play an important role in maintaining the structure and balance of ecosystems in these communities, therefore they are keystone species.

Answer:

A. Keystone species.

Explanation:

A species that has huge impact on the other in the case when there is not much abundant species. In addition to this, it would keep the other populations in the ecosystem. Moreover, if the species would be removed so this would lead in diversity loss

So according to the given situation, the role that played by  elephants in these communities is keystone species

is a heat pack safe for period pain ?

Answers

Answer:

I hope this hepls :)

Explanation:

Heat therapy is said to work because of its analgesic properties or its ability to bring blood to the area which can penetrate deep into the muscular tissue. However, heat therapy is also said to work because it is comforting on a psychological level. According to Lorimer Moseley “to reduce pain, we need to reduce credible evidence of danger & increase credible evidence of safety” and applying heat makes us feel safe. Why? Because the cold kills!  

Despite this, there is little evidence to show that it helps alleviate pain at certain trigger points  (small patches of acutely sensitive soft tissue) in the body and there is less evidence to show that it works for period pain. One study has claimed that heat can work for period pain however the researchers failed to differentiate if their exercise programme or the psychological effect of feeling warm eased their pain. This kind of testing means that other variables influence participants’ perception of pain and we can’t be certain if the heat therapy actually helped. What we do know is there are certainly drawbacks to this kind of treatment.

Answers

Answer:

B. the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5' end

Explanation:

Deoxyribonucleic acid, known as DNA, is the genetic material of a cell, which must first undergo replication i.e produce two identical copies of itself, before a cell can divide. During replication, the double stranded DNA unwinds into a replication fork consisting of two single strands of DNA.

These single strands of DNA are called leading strand (runs from 3'-5') and lagging strand (runs from 5'-3'). These single strands that runs at opposite direction from one another exists at the replication fork because the two strands of DNA are antiparallel i.e. are opposite to one another, and DNA polymerase can only add new nucleotides onto a 5' end.

Leading and lagging DNA strands exist at a replication fork because the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5 'end.

A replication fork is the juncture between two strands of DNA when it is replicating itself.

In each of them (speaking of the homologous strands) the opposite chain is carried out to have the double genetic information when approaching cell division.

The direction in which the enzymes act is unique from 5 'to 3', this determines the template chain must have the direction 3'→ 5', so that the new chain in formation, complementary and antiparallel, has the direction 5 '→ 3' coinciding with the enzyme's working system.

The basic reaction that takes place in replication is a polymerization reaction, in a growing DNA chain a nucleotide is incorporated whose base is complementary to that of the template chain.

The DNA polymerases at the two ends of the free nucleotide to be incorporated use its phosphate group or 5 'end to add it to the growing chain.

Therefore, we can conclude that leading and lagging DNA strands exist at a replication fork because the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5 'end.

A particular species of lizard can range in body color from dark brown to light brown. Body color influences how well an individual lizard can hide from predators. The more similar a lizard's body color is to the soil in its environment, the less likely it is to be seen by a predator The two graphs below represent two similarly-sized populations of lizards in similar environments that have medium-brown soil. Population 1 Population 2 Number of Individuals Number of individuals darker lighter darker lighter Body Color Body Color Suppose an environmental change that causes the soil color to become much different occurs in both environments. Which of the following is true? ​

Answers

Answer:

A- Population 1 is more likely to adapt and survive than population 2 because there is more variation related to body color in population 1.

Explanation:

In order for natural selection to occur, organisms within a population must have some genetic variation. That is, organisms within a population must have some traits that are different from one another. The more genetic variation that exists in a population, the better able the population is to handle environmental changes because it is more likely that at least some individuals will survive and reproduce.

The graphs show that population 1 exhibits a greater degree of genetic variation than population 2 in terms of body color. This means that if the soil in the environments where these populations live changes, it is more likely that some of the individuals in population 1 will survive and reproduce due to having advantageous body color in the new environment. Therefore, population 1 is more likely to adapt and survive than population 2 because there is more variation related to body color in population 1.
