In anencephaly, maximum of the brain and cranium do not develop. infants with anencephaly are normally both stillborn or die rapidly after birth.

a few babies have anencephaly because of a exchange in their genes or chromosomes. Anencephaly might also be as a result of a combination of genes and different elements, such as the matters the mom comes in touch with inside the environment or what the mother eats or liquids, or positive drugs she uses all through pregnancy.

This consequences in a lack of a chief part of the mind, skull and scalp. babies with Anencephalus are regularly stillborn. If the toddlers are born alive, they generally stay just a few hours or days.

NTDs occur when the neural tube does now not near nicely.

Answer:

Microbial enzymes are the preferred source to plants or animals due to several advantages such as easy, cost-effective and consistent production. The present review discusses the recent advancement in enzyme technology for food industries.

PAO won't be made if the gene is mutated. Because chlorophyll is not broken down, peas will continue to be green.

Most of the crop is yellow peas are dominant (Y). Green peas are recessive (y). Green-colored peas are still developing. Chlorophyll will degrade along the pathway as the pea ripens. In due course, the pea will become yellow.

The PAO enzyme catalyzes the breakdown of chlorophyll, so when the gene responsible for producing it is altered, the pea plant won't produce a functional PAO, which prevents the chlorophyll in that plant from being broken down. As a result, the pea plants won't turn yellow as predicted by Mendel's Law and will instead stay green.

The absence of PAO is caused by a gene mutation. The chlorophyll in the pea won't degrade, thus it will stay green.

The two pieces of evidence that support the theory of the expanding universe are the red shift of light from distant stars and the existence of cosmic background radiation.

The correct answer is option B.

1. Red shift of light from distant stars: The observation of redshift in the light coming from distant galaxies provides evidence for the expansion of the universe. Redshift occurs when the light waves from an object moving away from an observer are stretched, causing a shift towards longer wavelengths. This phenomenon is consistent with the Doppler effect, where the wavelength of light appears to stretch as the source moves away. The redshift of light from distant stars indicates that galaxies are moving away from us and from each other, supporting the idea that the universe is expanding.

2. Existence of cosmic background radiation: The discovery of cosmic background radiation further supports the theory of the expanding universe. Cosmic background radiation is a faint, uniform microwave radiation that permeates the entire universe. It is believed to be residual radiation from the Big Bang, the initial event that is thought to have initiated the expansion of the universe. The presence of cosmic background radiation provides strong evidence for the hot, dense early stages of the universe and its subsequent expansion.

C. When there is high selective pressure is genetic drift a major factor in evolution

Due to stochastic sampling error (i.e., genetic drift), small populations tend to lose genetic diversity faster than large ones. This is owing to the fact that certain variants of a gene might be lost due to random chance, which is more likely to occur in small populations.

Genetic drift is the accidental loss of genes from a population. In small populations, random variations in allele frequencies limit genetic variety, resulting in greater homozygozity and a loss of evolutionary resilience to change.

1. As objects move away from us, their light gets shifted into longer wavelengths or the red end of the spectrum — that's redshift. Blueshift is the opposite, when light is shifted to shorter wavelengths on the blue side of the spectrum as an object comes towards us.

2. When looking at the radiation emitted by distant stars or galaxies, scientists see emission spectra ‘shifted’ towards the red end of the electromagnetic spectrum—the observed wavelengths are longer than expected. Something causes the wavelength of the radiation to ‘stretch’.

A shift light is a warning lamp fitted to vehicles in order to indicate to the driver that maximum revolutions per minute (r/min) has almost been reached.

Moreover, the wavelength of light emitted by a moving object is shifted. This effect is called the doppler shift. If the object is coming toward you, the light is shifted toward shorter wavelengths, blue shifted.

Therefore, the larger the shift, the higher the speed of motion. The shifts in spectral lines can also be used to detect binary stars as they orbit around their center of mass and move toward and away from Earth. The shifts in spectral lines are an example of the Doppler Effect.

Answer: 13 is a trisomy

Explanation:

Answer:

The total amount paid for the loan can be calculated as follows:

Total amount = Principal + Interest

Where Principal is the amount borrowed, and Interest is the additional amount charged for borrowing the money.

Given:

Principal (P) = $3200

Interest rate (r) = 5% = 0.05 (as a decimal)

Time (t) = 4 years

Using the simple interest formula:

Interest = P × r × t

Interest = $3200 × 0.05 × 4

Interest = $640

Therefore, the total amount paid for the loan is:

Total amount = $3200 + $640

Total amount = $3840

Hence, the total amount paid for the loan is $3840.

Option (D) is the proper response because irrigation can raise the amounts of nitrogen and phosphorus in soil and water to risky levels, affecting ecosystem animals and plants.

The potential over-extraction of groundwater for irrigation has the potential to have direct detrimental environmental effects (withdrawing water in excess of the recharge rate). This may cause the water table to drop, land to sink, water quality to deteriorate, and saltwater intrusion in coastal areas.

Compared to sprinkler irrigation, flood irrigation loses less water to evaporation, but more water may be lost through runoff in the fields. The major reason we parameterize the irrigation techniques is to reflect their unique water use effectiveness.

Answer:

No adaptive immune responses would occur during pathogen attack

Explanation:

The lymphatic vessels are required in the migration of dendritic cells and to transport antigens from the interstitium of peripheral tissues to the lymph nodes, in which the T cells are activated to become effector cells. Moreover, the T (and B) effector cells move through lymph vessels to encounter those antigens presented by dendritic cells. In consequence, the lymphatic vessels have critical functions during adaptive (acquired) immune responses.

Answer:

carbon dioxide in the atmosphere that we don't see or feel because its effects are happening underwater. At least one-quarter of the carbon dioxide (CO2) released by burning coal, oil and gas doesn't stay in the air, but instead dissolves into the ocean. Since the beginning of the industrial era, the ocean has absorbed some 525 billion tons of CO2 from the atmosphere, presently around 22 million tons per day.

At first, scientists thought that this might be a good thing because it leaves less carbon dioxide in the air to warm the planet. But in the past decade, they’ve realized that this slowed warming has come at the cost of changing the ocean’s chemistry. When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean’s pH (a measure of how acidic or basic the ocean is) drops. Even though the ocean is immense, enough carbon dioxide can have a major impact. In the past 200 years alone, ocean water has become 30 percent more acidic—faster than any known change in ocean chemistry in the last 50 million years.

Scientists formerly didn’t worry about this process because they always assumed that rivers carried enough dissolved chemicals from rocks to the ocean to keep the ocean’s pH stable. (Scientists call this stabilizing effect “buffering.”) But so much carbon dioxide is dissolving into the ocean so quickly that this natural buffering hasn’t been able to keep up, resulting in relatively rapidly dropping pH in surface waters. As those surface layers gradually mix into deep water, the entire ocean is affected.

Such a relatively quick change in ocean chemistry doesn’t give marine life, which evolved over millions of years in an ocean with a generally stable pH, much time to adapt. In fact, the shells of some animals are already dissolving in the more acidic seawater, and that’s just one way that acidification may affect ocean life. Overall, it's expected to have dramatic and mostly negative impacts on ocean ecosystems—although some species (especially those that live in estuaries) are finding ways to adapt to the changing conditions.

However, while the chemistry is predictable, the details of the biological impacts are not. Although scientists have been tracking ocean pH for more than 30 years, biological studies really only started in 2003, when the rapid shift caught their attention and the term "ocean acidification" was first coined. What we do know is that things are going to look different, and we can't predict in any detail how they will look. Some organisms will survive or even thrive under the more acidic conditions while others will struggle to adapt, and may even go extinct. Beyond lost biodiversity, acidification will affect fisheries and aquaculture, threatening food security for millions of people, as well as tourism and other sea-related economies.
