How can homologous structures be used as evidence for shared common ancestry?

Answers

Answer 1
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. They all have the same basic pattern of bones. They inherited this pattern from a common ancestor. However, their forelimbs now have different functions

When an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex lowers the activation energy of the reaction and promotes its rapid progression by providing certain ions or chemical groups that actually form covalent bonds with molecules as a necessary step of the reaction process.

(Presumably, the reason it stung when I got it in my eyes was that the enzymes would also happily break down eye goo in an intact eye.) In this article, we’ll look in greater depth at what an enzyme is and how it catalyzes a particular chemical reaction.

Enzymes and activation energy

A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.

Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

How are adaptations passed to offspring?



Group of answer choices

Adaptations skip generations in organisms. Even if one organism "learns" an adaptation, it will be their "grandchild" organism that gets it.

Adaptations are mostly random, as they are genetic. They are written in the DNA. Changes in genes are random. If a mutation happens and the offspring of two parents has a mutation, sometimes that mutation will help it live.

The parents develop during their lifetime, so their DNA changes, and when they mate, the adaptation and then pass it on to offspring

Parents purposely CHOOSE which adaptations they give to their offspring, because they can choose which half of their genes are going to go into that organism, and predict how it will mix with it's mates genes. it is planned out to ensure species survival. This is especially true in flowering plants.

Answers

In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species.

Therefore, the answer is :

Adaptations are mostly random, as they are genetic. They are written in the DNA. Changes in genes are random. If a mutation happens and the offspring of two parents has a mutation, sometimes that mutation will help it live.

What is the structure of a virus?

Answers

Answer:

The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.

A virion consists of a nucleic acid core, an outer protein coating or capsid, and sometimes an outer envelope made of protein and phospholipid membranes derived from the host cell. The capsid is made up of protein subunits called capsomeres. Viruses may also contain additional proteins, such as enzymes

Explanation:

Answer:

The primary way that animals grow and develop is by building more cells. When an animal eats food, its body breaks the food down and uses it to fuel its energy requirements and build new cells through the process of mitosis. These new, or daughter, cells are often similar in size to the old, or parent, cells.

Describe how you will estimate the rate of photosynthesis.

Answers

Explanation:

there are various methods to measure photosynthesis: Uptake of CO2 by plants: Since CO2 is needed for photosynthesis, measuring how much of it is taken up by the plants gives us information on how much of photosynthesis is happening. Release of O2: The amount of O2 produced during photosynthesis can be measured.

Estimation or measuring the rate of photosynthesis can be done by:

by the production of oxygenthe uptake of carbon dioxideIndirectly by an increase in biomass.

The rate of photosynthesis is a gross measure of the rate at which a plant captures radiant energy and fixes it in organic carbon compounds. It can be estimated by:

Depletion of the substrate that is carbon dioxide, has been used or how much water is used.the accumulation of oxygen is a measure of the rate of reaction.measure the rate of photosynthesis in leaves by observing the release of oxygen

DNA sequences can act as "tape measures of evolution." Some highly-conserved regions of the human genome (similar to comparable regions in other species) don't code for proteins. Why?
1. Such regions coded for proteins in genomes of distant human ancestors, but over time they became noncoding; however, conserving their sequence remained unchanged.
2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.
3. Such regions are the sites of DNA recombination. They should remain conservative to provide an accurate recombination process during cell division.
4. Such regions remain conservative because the mutation rate differs along the genome. In other words, such regions remain conservative accidentally.

Answers

Answer:

2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.

Explanation:

Within the genome there are many non-coding regions that control the expression of master developmental genes such as, for example, Hox major transcription factors (TFs) in animals and MADS-box TFs in plants. These gene regulatory regions (e.g., promoters and enhancers) are generally evolutionarily conserved within certain taxonomic groups. In consequence, such non-coding regions are well known to be conserved and interact in a sequence-specific manner with major transcription factors in order to regulate developmental pathways.

Los receptores olfatorios son células especializadas capaces de percibir miles de sustancias químicas diferentes y decodificar la información en miles de olores distintos. Estos receptores se localizan en la mucosa nasal de las fosas nasales. En el caso del olor a rosa, como así también cualquier otro olor, las sustancias químicas responsables del olor se dirigen al epitelio olfatorio de la mucosa nasal, donde se unen a receptores específicos localizados sobre filamentos sensoriales (cilios) en las membranas celulares de las neuronas especializadas. La unión desencadena una respuesta en la células neuronales, es decir, una descarga eléctrica que se propaga desde las fosas nasales hasta el cerebro, el cual decodifica la información (el olor) en una región conocida como bulbo olfatorio.

Place 14 oz of crushed ice into a small pot. Then add about 125 mL of water to it.

Using the thermometer, measure and record the initial temperature of the ice water. List this temperature in °C in the “0” minutes row of your data table in the lab handout. *Do not allow the thermometer to touch the bottom of the pot when recording measurements.

Place the pot on the stove, and turn the knob to the medium-low setting.

Using the thermometer, measure the temperature every minute until the water begins to boil vigorously. Record this data in the table on your lab handout.

At each measurement, also record what is happening to the water. Be sure to record the times of these events:

The ice melts.

The water forms steam.

The water begins to boil.

Once the water has begun to boil, stir the water constantly with the spoon.

Continue to measure and record the temperature every minute until almost all the water has boiled and the pot is close to empty.

Record the last temperature, and turn off the stove. DO NOT TOUCH THE POT WITHOUT SAFETY EQUIPMENT.

Create the x-axis and y-axis of a graph.

Label the x-axis as follows: Time (min).

Label the y-axis as follows: Temperature of Water (°C).

Along the x-axis, create and label 15 marks, one for each minute of the experiment. (Hint: The origin starts at 0.)

Along the y-axis, create and label temperature markings for every 20 degrees. (Hint: The origin starts at 0.)

Refer to the data from your experiment to plot the points on your graph. Then connect each of the data points with a line.

Look over your graph to make sure it is clear and correctly labeled.

Either save your graph as a computer file, or take a picture of your graph and upload it as a file on your computer.

How do the distances between the terrestrial plants compare to the distances between the gas giants?

Answers

Answer:

They are different from rocky or terrestrial planets that are made of mostly rock. Unlike rocky planets, gas giants do not have a well-defined surface – there is no clear boundary between where the atmosphere ends and the surface starts! The gas giants have atmospheres that are mostly hydrogen and helium.

Explanation:

I hope this helps!

They vary from planets that are predominantly made of rock, such as rocky or terrestrial planets. Unlike solid planets, gas giants lack a clearly defined surface, there is no discernible line separating the atmosphere from the surface.

What are terrestrial planets?

Telluric planets are another name for terrestrial planets. The Latin words terra and tellus, which both indicate Earth, are the source of the words terrestrial and telluric, respectively.

While the terrestrial planets were warmed by the sun's rays, the Jovian planets developed above the frost line.

Worlds that could float on water and worlds appropriate for manned missions were created under very distinct circumstances, but they have some striking similarities. Every world in our solar system is different.

Therefore, the atmospheres of the gas giants are primarily composed of hydrogen and helium.
