how extrusive igneous rocks and intrusive igneous rocks form?
Answers
Answer:
Intrusive igneous rocks are formed when magma cools slowy and large crystals are formed
Extrusive igneous rocks are formed when magma cools quickly, and small or no crystals are formed, it may be vesicular meaning it may contains air bubbles.
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.

catalyzed particular chemical reactions – in this case, reactions that broke down the film of eye goo that accumulated on my contacts after a week of use. (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.
How is passive transport different from active transport?
A) Passive transport is substances moving from HIGH concentration to LOW concentration.
B) Passive transport requires energy input.
C)Passive transport happens regardless of concentration gradient.
D) Passive transport is substances moving from LOW concentration to HIGH concentration.
ASAP
Answers
Answer:
A
Explanation:
Passive transport does not require energy. The substances follow the concentration gradient, meaning they go from high to low. Active transport goes against the concentration gradient. Substances go from low to high, so it requires energy.

¿Qué receptores se estimulan al oler la rosa? Explica el proceso a través del cual se percibe el aroma de la rosa.
Answers
Answer:
receptores olfativos especializados localizados en el epitelio olfatorio de la mucosa nasal
Explanation:
Las neuronas receptoras del olor se denominan receptores olfatorios. 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.

Answers
Answer and Explanation:
Lipids are non-polar molecules, so they do not interact preferentially with polar molecules but they can interact with each other. In a polar medium, such as water, the hydrocarbons in lipids aggregate each other, in order to minimize contact with surrounding polar molecules. The interaction between non-polar solutes with polar surroundings exclusion is called hydrophobic interaction.

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.

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:

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
