Why do you think it is functionally important that the bones of the os coxae fuse together rather than remain independent bones

Answers

Answer 1

Answer:

Provides more strength.

Explanation:

It is functionally important that the bones of the os coxae fuse together rather than remain independent bones because the fusion of bones of the os coxae increases their strength and they can perform their function very well. If the fusion of bones of the os coxae did not occur and they remain independently so they can't bear the load of the body and so the function is also adversely affected.

One moth population carries three alleles at a genetic locus: X1, X2and X3. X1is dominant to X2and X3; X1produces red antennae. X2is co-dominant to X3; X2X2produces yellow antennae, X3X3produces white antennae, and X2X3produces light yellow antennae. The phenotypes in a population are as follows: 0.04 white; 0.16 light yellow; 0.16 yellow; 0.64 red.Assuming that this population is in Hardy-Weinberg equilibrium, what is the frequency of the X3allele in this population

Answers

Answer:

The correct answer is - 0.20

Explanation:

According to Hardy Weinberg equation under specific conditions the frequencies of the allele in the gene in a given population remain constant. Thus according to this frequencies of allele and genotype will remain the same through the generation unless there will be no evolutionary influence.

It helps us to predict the genotype frequencies in a large population.  If there are two alleles having allelic frequencies p and q and we know equation of probability and frequencies add to 1

p2+2pq+q2=1

The X3X3 genome produces white antennae. Now Phenotypic frequency of the white antennae is 0.16 or 0.04 in the whole population. Hence the frequency of X3 should be a square root of 0.04 i.e, 0.20.

We have all heard about earthquakes or the cyclones that attack the coastal regions. Think of as many different ways as possible in which people's health would be affected by such a disaster if it took place in our neighbourhood. (a) How many of these health -related events would occur long after the actual disaster, but would still be because of the disaster? (b) How can it affect the life of people if in case of a pandemic?

Answers

Answer:

The disease spread to the neighbourhood.

Explanation:

If the disaster such as earthquake and pandemic etc occurs in the neighbourhood so it also affected the health of the people of that region as well as the people that lives in the neighbourhood. In the case of pandemic, the disease spread to the neighboring area and affect the health of people while on the other hand, in earthquake the people of neighbourhood is also affected if the intensity of earthquake is higher.

Approximately how many mutations occur naturally in DNA per 10,000 bases?
A. 2
B. 2000
C. 200
D. 20

Answers

Explanation:

Modern methods indicate that the mutation rate is roughly one to two mutation per 10,000 genes per generation.

In human cells, approximately TWO (2) MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).

The mutation rate (u) refers to the occurrence of new mutations in a given nucleotide sequence over time.

In human cells, the mutation rate is approximately 10⁻⁴ per generation.

Therefore, in a DNA sequence that has 10,000 base pairs of length, this value is equal to 2 mutations per generation (u = 2 / 10,000 = 10⁻⁴).  

In conclusion, approximately 2 MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).

What does the word Photosynthesis mean?

B. Creating photographs.
C. Taking apart with light.
D. Putting together with light.

Answers

Answer:

A

Explanation:

release of energy through the breakdown of glucose

The release of energy through the breakdown of Glucose means Photosynthesis.

Photosynthesis

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs  "light", and synthesis  "putting together" Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere and supplies most of the energy necessary for life on Earth.

Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other colored) pigments/chromophores. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas.

Answers

Answer:

See explanation

Explanation:

The introduction of nonnative species in an ecosystem maybe both helpful and harmful. Initially, the introduced nonnative species maybe prove helpful in some ways.

As time goes on, the nonnative species begin to compete with the native species for resources in the ecosystem. The nonnative species may outdo the native species in such competition and entirely replace them. This may ultimately lead to a permanent loss of the native species from the ecosystem.

What are change of state?

A state is physical condition of any substances it means that any substance which found on earth are mainly found in three states and these are following:-

1- Solid

2- Liquid

3- Gas

A change of state is physical change of state i.e any substance which changes their state from ( solid to liquid called melting), (liquid to gas called evaporation), (gas to solid called diffusion) etc  are called change of state.

These change of state occurs when temperatures or pressure changes in a system or substances. When the temperature or pressure increase  the interaction between the molecules also increases.

What type of unconformity did Hutton see at Siccar Point and how was this uniformity formed?

Answers

Answer:

Hutton's Unconformity

At Siccar Point, during the lower Silurian Llandovery epoch around 435 million years ago, thin beds of fine-grained mudstone were laid down gradually deep in the Iapetus Ocean, alternating with thicker layers of hard greywacke formed when torrents swept unsorted sandstone down the continental slope. Siccar Point is a rocky promontory in the county of Berwickshire on the east coast of Scotland. It is famous in the history of geology for Hutton's Unconformity found in 1788, which James Hutton regarded as conclusive proof of his uniformitarian theory of geological development.

Some birds on the Galapagos Islands build nests in trees, while others hide eggs in rock crevices. What could account for this difference in nesting behaviors?

Answers

Answer:

Food habits, predators.

Explanation:

The biggest reasons are food habits and predators, most birds who nest on the ground either can't fly or use this to be closer to their food. A ground bird (Like quail) can fly but choose to be more ground-based birds.

Most of the time it's because these birds forage for food like ground insects, seeds from the brush that grows on the ground, or fallen fruit.

Most birds that live in the trees feast on seeds, leaves, or insects found close to where they choose to nest. They may also want to escape any predators that may be towards the ground.
