Answer:

Secondary endosymbiosis is when a living cell engulfs another eukaryote cell that has already undergone primary endosymbiosis. It has happened often enough that it has led to genetic diversity among the organisms on Earth.

Explanation:

The closer together two genes are on a chromosome, the less likely their alleles will be separated by crossing-over.

Answer:

Human population growth impacts the Earth system in a variety of ways, including: Increasing the extraction of resources from the environment. These resources include fossil fuels (oil, gas, and coal), minerals, trees, water, and wildlife, especially in the oceans.

Explanation:

DNA evidence and the fossil record indicate are the ancestors of the living cetaceans were land-dwelling mammals. DNA evidence allows to trace the evolutionary origin of taxonomic groups.

DNA evidence refers to the linear order of nucleotides, which can be used to trace the evolutionary origin of a particular taxonomic group.

When the linear order of DNA nucleotides is conserved, it is known as sequence homology.

Fossils are preserved remains of organisms that once lived on the Earth, which can also be used as evidence to trace the evolutionary origin of a given group.

Answer:

Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 1). Because they use light to manufacture their own food, they are called photoautotrophs (literally, “self-feeders using light”).

Explanation:

Bb x Bb

1BB, 2Bb, and 1 bb

Let B=black fur allele(dominant) and b=white fur allele(recessive),

¾ of the rabbit will be black while ¼ will be white.

Hence,

¾×100%=75%

¼×100%=25%

Answer:

The geologic features related to convergent boundaries vary depending on crust types. Plate tectonics is driven by convection cells in the mantle. ... Subduction begins when this dense crust converges with less dense crust. The force of gravity helps drive the subducting slab into the mantle

An archegonium (pl: archegonia), from the ancient Greek ἀρχή ("beginning") and γόνος ("offspring"), is a multicellular structure or organ of the gametophyte phase of certain plants, producing and containing the ovum or female gamete. The corresponding male organ is called the antheridium.

Research studies are often carried out using mouse. From the study, the simulated mice was said to align with the predictions from the Punnett squares. So the answer is Yes.

The reason why some of the percentages did not exactly match your predicted results because the Mice don't have large litters, so the sample size was not large enough.

If the experiment is to be done again, I can improve upon experimental design by;

A lot of studies is been carried out on the Genetics of the mouse.  The  early development of inbred lines were studied. The mouse is known to be a good tool to identify the genetic basis of both normal and disease traits.

Answer:

The answer is yes....

Explanation:

The greatest number of relationships between the organisms in an ecosystem is best shown in a food web. Thus, the correct option is C.

A food web consists of all the food chains which are present in a single ecosystem. Each of the living thing in an ecosystem is a part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem.

For example- A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. It is a food web that shows the many different paths plants and animals are connected.

Therefore, the correct option is C.

Answer:

interferes with release of neural transmitter GABA

Explanation:

Alcohol is a central nervous system depressant, meaning it slows down brain functioning and neural activity. Alcohol does this by enhancing the effects of the neural transmitter GABA

depressants essentially "look" like the neural transmitter and so they go in and block the plasce in the brain between synapses, so when the body tries to release GABA, it appears as if it is already filled in, but in reality it is the alcohol that has filled it. once they start buidling up, they block enough that it impairs brain activity

Answer:

GABA

Explanation:

gamma-aminobutyric acid (GABA)

all cells life begin and end with this process by the process of meiosis

Meiosis is the process  where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.

Humans have 46 chromosomes in every cell,  where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.

Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.

Secondly Prometaphase I where Spindle fibres attach to the  centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.

Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.

The following tracking model was created for Hurricane Ike on September 8, 2008. Map of Gulf Coast showing the forecasted path of Hurricane Ike on September 8, 2008. The storm’s current location, as of 5 p.m. on Friday, is just south of Cuba, over the Caribbean Sea. The “cone of probability” extends northwest. Point A is located along the Texas coast, right in the center of the cone’s widest point. Point B is located along the coast of Louisiana, toward the easternmost edge of the cone. Point C is located further east, along the coast of the Florida Panhandle. Point D is located on the border between Mexico and Texas, toward the southwestern-most edge of the cone. According to this model, at which point is the storm least likely to make landfall?

The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.

Answer:

D

Explanation:

ATP is created in the ETC

Water is formed as a by product

The concentration gradient is what fuels the ETC. Protons (H+ ions) move across the membrane to create energy.
