can oxygen diffuse across the cell membrane?
Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion or a type of diffusion known as osmosis. diffusion is one of the principal method of movement of substances within sales, as well as the method for essential small molecules to cross the cell membrane.

How can a gene that contains introns be made shorter for genetic engineering purposes? What does it use and how does it use it?
Answer:
reverse transcriptase to reconstruct the gene from its mRNA
Explanation:
Genetic engineering may be defined as the process of using the recombinant DNA (rDNA) technology in order to alter the genetic makeup of the organism. It is also called as the genetic modifications. It uses the science of biotechnology to modify and manipulate the genes of an organism.
A gene containing introns can be made shorter and still remain functional for the genetic engineering purposes by using the reverse transcriptase for reconstructing the gene from the mRNA.
It uses the reverse transcriptase of the mRNA.

Answer:
The water is transported to the top most leaves (and rest of its parts) of a tall tree by three actions:
1) root pressure (osmosis)
2) capillary action (adhesion)
3) evapotranspiration (cohesion)
Explanation:
The trees contain a series of interconnected tissues (xylem and phloem) that act as network for transport of water and nutrients throughout the tree. The root pressure and capillary action push the water, while the transpiration from the leaves pull the water. The root pressure is generated by osmotic movement of water from soil to the root tissues. The capillary action is caused due to adhesion of water molecules. However, root pressure and capillarity is thought to support only few meters of water column. The rest of the water transport (esp. in tall trees) is attributed to negative pressure generated by evaporation of water from leaves. This negative pressure creates a vacuum and pulls the water from the roots.

which igneous rock could physically weather to beach sand that contains the minerals pyroxene, plagioclase, feldspar, and olivine?
Answer:
gabbro
Explanation:
just took the test!
An igneous rock which could physically weather to beach sand that contains the minerals pyroxene, plagioclase, feldspar, and olivine is: Gabbro.
Weathering refers to both the chemical and physical breakdown of a rock into smaller fragments (pieces) referred to as sediments.
Generally, there are two (2) main types of weathering and these are;
1. Chemical weathering.
2. Physical weathering.
Gabbro is a coarse-grained (phaneritic), mafic intrusive type of igneous rock which physically weather to beach sand containing the following sediments or minerals:

Answer:
for the first one, its most likely light morph, for the second one dark morph
Explanation:
Birds are sight hunters so that means that they look for their food so in this case the moths on the dark tree that has a dark morph will not be seen but the moth with light morphs on a dark tree will be seen and eaten, and the opposite with light trees but if the tree is speckled the speckled moth will survive depending on the color of the tree. I hope this wasn't too confusing for you.
Most electricity in the United States is generated using coal, natural gas, nuclear energy, or hydropower. Which of these add carbon dioxide to the atmosphere?
A. coal and natural gas
B. natural gas and nuclear energy
C. nuclear energy and hydropower
D. hydropower and coal
Answer:b
Explanation:
Most electricity in the United States is generated using coal, natural gas, nuclear energy, or hydropower, and coal and natural gas add carbon dioxide to the atmosphere, which is Option A.
What is the significance of the electricity and energy systems?Coal and natural gas contain large amounts of carbon, which are released into the atmosphere as carbon dioxide when burned and contribute to global warming and climate change and on the other hand, nuclear energy is generated through the controlled release of energy from the nucleus of an atom. This nuclear energy does not release carbon dioxide, while hydropower is generated from the movement of water.
Hence, most electricity in the United States is generated using coal, natural gas, nuclear energy, or hydropower, and coal and natural gas add carbon dioxide to the atmosphere, which is Option A.

The DNA strand and pre-mRNA strand are anti-parallel. With this in mind label the 3' and
5' ends of the pre-mRNA strand in Model 1. Where would i put it??
Answer:
I think the right side is 3 prime and left sde is 5 prime
Explanation:
Because the process of transcription takes place in nucleus so it should be put inside the nucleus.
What is nucleus?In genomics, a nucleus is a membrane-enclosed organelle within a cell that houses the chromosomes.
What is Transcription?The process in which information of a strand of DNA is copied into a new m RNA molecule is known as Transcription.
The enzyme responsible for transcription is RNA polymerase. Transcription start when RNA polymerase binds to a promoter region at the start of a gene directly or through helper proteins. Initiation, Elongation, and termination are the three steps of transcription. Transcription is carried out with the help of enzyme RNA polymerase and some proteins known as transcription factors. Enhancer and promoter sequences are the DNA sequences on which transcription factors attach to initiate the transcription process by directing RNA polymerase to the correct transcription site.The transcription initiation complex is made up of transcription factors and RNA polymerase working together.

how does respiration take place in insects?
Answer:
please give me brainlist and follow
Explanation:
Instead of lungs, insects breathe with a network of tiny tubes called tracheae. Air enters the tubes through a row of holes along an insect's abdomen. The air then diffuses down the blind-ended tracheae. Since the biggest bugs have the longest tracheae, they should need the most oxygen to be able to breathe.
