According to the research, the correct option is endomembrane system. In eukaryotes, the endoplasmic reticulum, golgi apparatus, lysosomes, vacuoles, nuclear envelope, and plasma membrane form a network of membranes called the endomembrane system.

It is the set of internal membranes that divides the cell into compartments formed by ER, Golgi complex, endosomes, lysosomes and nuclear envelope, all these organelles are members of the same family and communicate intensely with each other and with the outside of the cell via transport vesicles.

In this sense, it makes it possible to compartmentalize its interior, creating different spaces in which reactions can be carried out, participating in the production of cytoplasmic organelles.

Therefore, we can conclude that according to the research, the correct option is endomembrane system. In eukaryotes, the endoplasmic reticulum, golgi apparatus, lysosomes, vacuoles, nuclear envelope, and plasma membrane form a network of membranes called the endomembrane system.

It is true that in fermentation, the only ATP produced was during glycolysis and the fermentation reactions usually result in resetting the NADH to NAD.

Fermentation is the process of breakdown of sugars to yield lactic acid or alcohol, along with some energy. This process occurs in the absence of oxygen and the by-products of the reactions are heat and an effervescence of CO₂. Fermentation commonly occurs with the help of yeasts.

Glycolysis is the process of breakdown to sugar to yield pyruvate. it occurs without the help of oxygen and is common process in both aerobes as well as anaerobes. The net gain of energy from glycolysis is of 2 ATPs and 2 NADH molecules.

What is a haploid?

A cell is said to be haploid if it only has one set of chromosomes. The number of copies of the genome is referred to as ploidy. Numerous other organisms, including humans, are diploid. This indicates that each cell contains two copies of the genome for the bulk of its whole existence. Haplotype cells are often produced for reproduction. One copy of the genome allows for the reorganization of various copies during zygote formation. Numerous novel DNA combinations are made available in the progeny by making the DNA content of the gametes haploid. This boosts genetic diversity and aids in population climate adaptation.

The correct answer for this question is RhoGAM administration

RhoGAM is an antibody solution derived from plasma donors. RhoGAM is being prescribed by your doctor because you are Rh-negative. It is normal for a small amount of the baby's blood to enter your bloodstream during pregnancy. There will be a blood type mismatch when the blood from your Rh-positive baby enters your Rh-negative bloodstream. This is known as Rh incompatibility. Your immune system recognizes the baby's red blood cells as "foreign," and antibodies are produced to try to eliminate them. If you take RhoGAM at the right time, it will keep your immune system from reacting to your baby's blood. RhoGAM is made from human blood and may carry a risk of transmitting disease-causing agents.

Option c. is correct. Secondary minerals are most prominent in the clay fraction of soils.

Soil minerals are a natural source of plant nutrients that are released gradually over time as a result of chemical weathering. While secondary minerals are a byproduct of chemical weathering and are formed either by partial chemical alteration of primary minerals or by chemical precipitation from the reaction of components dissolved from other minerals.

The majority of secondary minerals are soil-stable hydrated aluminosilicates or Fe and Al oxyhydroxides. The majority of hydrated aluminosilicates are phyllosilicates also known as clay minerals, which are the most common secondary minerals in Canadian soils.

The fraction of clay minerals is fundamentally different from the sand and silt fractions, not only in grain size but also in mineralogy. It typically contains secondary minerals which are by-products of chemical weathering and re-precipitation. Although some clay minerals are amorphous, crystalline clay minerals are the most common.

Answer:

140 km per hour.

Explanation:

350 divided by 2.5= 140

The average speed of the train was 140 kilometers per hour.

Speed ​​is a unit used to describe how fast something is moving with respect to another object. Due to its scalar nature, it has only magnitude and no direction. By dividing the distance traveled by an object by the time required to cover that distance, one can calculate its speed.

The formula for calculating speed is as follows:

Speed = Distance / Time

In the International System of Units (SI), the meter per second (m/s) is the accepted unit for measuring speed. Nevertheless, other common units for speed include kilometers per hour (km/h) and miles per hour (mph), depending on the situation and location.

We can use the following calculation to determine the typical speed of a train:

Average speed = Distance traveled / Time taken

In this example, the train covered this distance of 350 km in 2.5 hours.

Average speed = 350 km / 2.5 hours

Average speed = 140 km/h

Therefore, the average speed of the train was 140 kilometers per hour.

(D) in highly diverged lineages, substitutions will occur at sites that have been substituted previously is the reason why the molecular clock has limited usefulness for estimating divergence times among species in part due to the saturation of dna sequences.

The frequency of a molecular clock represents the quantity of alterations or mutations that have occurred in a lineage of organisms' DNA or protein sequences. It can be used to estimate the historical moment at when two lineages separated from one another.

However, modifications may occur more than once for a particular site in highly divergent lineages (i.e., those lineages that were divided extremely far back in evolutionary time). As a result, and in part because of the saturation of DNA sequences, it won't be useful for estimating divergence periods among species.

A. DNA sequences are unable to revert back to previous allelic states.

B. the variation in the substitution rate between closely related lineages prevents accurate estimation of divergence time.

C. variation in population sizes among lineages changes the effect of genetic drift.

D. in highly diverged lineages, substitutions will occur at sites that have been substituted previously.

Answer:

The molecular clock has limited usefulness for estimating divergence times among species in part due to the saturation of DNA sequences. This occurs because In highly diverged lineages, the substitutions process will occur at sites that have been substituted previously.

Explanation:

The mutation rate is used by the molecular clock to shorten the ancient period during which living forms separated. Both amino acid sequences plus DNA's nucleotide sequences are used by the molecular clock.

Only the percentage of mutations as well as other modifications over a predetermined period of time are recorded by this clock. Frequently, a property's usefulness may be restricted by the lineages' extreme diversity. The researchers come to the conclusion that molecular clocks are significantly so "erratic" comparatively previously believed, making them essentially worthless for maintaining precise evolutionary time. They blame natural selection's biases, which can occasionally prevent particular genetic mutations in particular lineages.

In mineralogy, luster refers to how a mineral surface appears in terms of its capacity to reflect light. The degree of transparency, diaphaneity, and structure of a mineral all affect its luster.

A mineral's ability to reflect light is referred to as luster. The first step in identifying a mineral is to measure it. Always examine a brand-new surface for luster; you might need to remove a tiny amount of material to reveal a clean sample. Metallic luster, which is extremely reflective and opaque, to dull luster (non-reflective and opaque.)

Mineralogists use the physical characteristic of luster to identify minerals. A mineral's luster defines how its exterior reflects light and how its inside may bend or refract light. Some minerals have a metallic sheen, while others don't.

A mineral reflects light by having a luster. The two main categories of luster are described by the labels metallic and nonmetallic.
