Answer:
The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.

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.

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.

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.

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:
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.

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.
