Answer:

Artificial selection can help solve human problems since humans can choose the desired traits of an organism to coordinate with their needs.

Explanation:

Since artificial selection is predictable, it is easier for humans to "customize" the traits of an organism to get a desired trait.

Answer:

The mechanisms of transport across the cell membrane are as follow: 1- simple diffusion, 2- facilitated diffusion, 3- primary active transport and 4-secondary active transport

Explanation:

The cell membrane is a selectively permeable structure capable of transporting substances by different mechanisms. Simple diffusion is a type of passive transport (i.e. does not require energy) where non-polar molecules (e.g. O2, CO2) pass across the membrane by a process that does not require energy from the cell. Facilitated diffusion is another type of passive transport where larger polar molecules (e.g., glucose and amino acids) pass across the membrane by using specific transmembrane integral proteins. On the other hand, primary active transport is a type of active transport that uses chemical energy (e.g., ATP) to move substances such as metal ions (Na+, K+, Ca2+) across the cell membrane against their concentration gradient. Finally, secondary active transport is another type of active transport where transporter proteins are used to couple the movement of ions (e.g., H+ protons) down their electrochemical gradient to the transport of another ions/solutes against their concentration/ electrochemical gradient.

Answer: c

Explanation:

Answer: True

Testable claims, or verifiable claims, are claims where we can prove them true or false. We do so by gathering/observing data, then afterward we see if the data fits the claim or not. If not, then we adjust the claim or we throw it out entirely.

Answer:

Ozone, 3.

Explanation:

Ozone is a molecule of oxygen with  3 oxygen atoms instead of 2 that is present in the atmosphere of the earth. It is a very important gas because this gas filter the solar radiation  from ultra violet radiation which causes skin cancer disease. Ozone is present in the stratosphere layer of atmosphere that is present between 15 to 30 kilometer high from the earth surface.

Eu" means "true," and eukaryotes have DNA arranged in chromosomes and encased in a nucleus. Fossil evidence indicates that prokaryotic cells first existed on the earth, prior to the arrival of the eukaryotes.

Explanation:

Reconstruction was the period in the united states during which the Civil war took place and the laws were made to provide equity to the slaves ending slavery.

The problem arises due to the reunion of the 11 states of the South to the Union which seceded earlier.  Slavery was more practised in the Southern states compared to Northern states.

The Republican party did corruption from 1869 to 1877 which allowed due to which they lost their election of 1877.

In 1877, a special electoral commission was established in favour of Hayes and Democrats took benefits of this condition.

When Hayes was selected, he withdrew the federal troops from the South which allowed the Democrats to gain their seats in South and ended Reconstruction.

Answer:

B

Explanation: i hope this is the answer

From the equator to the poles, the temperature of the Earth's surface normally drops. A biome's moisture content is influenced by both precipitation and evaporation, hence option B is correct.

Climate is the most important abiotic factor affecting the distribution of terrestrial biomes.

Temperature and precipitation are the primary determinants of plant growth. The plant will be discovered at that temperature and precipitation will be determined by the biome's temperature.

A biome's climate is mostly determined by the forms of life that exist there. Latitude, geographic characteristics, and atmospheric processes that disperse heat and moisture are only a few of the variables that affect climate. Scientists disagree on the number of distinct biomes that exist.

Therefore, temperature determines the distribution of biomes on the planet.

Answer:

A-G-C-U-C-A

Explanation:

A-G-C-U-C-A is the base sequence correctly represents the corresponding portion  of RNA molecule if DNA molecule with the base sequence A-G-C-T-C-A was used as a template. It is because the RNA molecule is formed from the same bases used in DNA except thymine. In RNA molecule, instead of thymine, uracil is attached with other nucleotide bases.

Answer:

The reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms. IN HYDROGEN ATOMS  It takes six atoms of carbon (C) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6). These atoms come from carbon dioxide (CO2) and water (H2O). IN OXGYEN It takes six atoms of carbon (C), six atoms of oxygen (O) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6).

In photosynthesis, the reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.

Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants. After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

Explanation:

Explanation:

Having filtered out small essential molecules from the blood - the kidneys must reabsorb the molecules which are needed, while allowing those molecules which are not needed to pass out in the urine. Therefore, the kidneys selectively reabsorb only those molecules which the body needs back in the bloodstream.

Answer:

Answer:

The correct answer is - 50%

Explanation:

In the heterozygous condition, there is always one allele of dominant and one allele of recessive present together and during gamete formation, they assort independently. The probability of the pink flower that is RW can be found by punnet square:

      R     W

R    RR   RW

W   RW    WW

here, out of four two cases is of heterozygous or pink flower so the ration would be 2/4 or 1/2 or 50%

Answer:  1. phospholipid bilayer 2. This is carbon-13, an isotope of carbon

Explanation:1. Two layers of phospholipid form the membrane, with their hydrophilic ends inwards. The hydrophobic surfaces protect the cell from osmotic changes by isolating the cytoplasm from the environment - except for embedded transport mechanisms for moving ions and molecules in and out as required.

2. C-13 is a rare, stable isotope of carbon, making up about 1% of natural carbon.

An element is defined by the number of protons in the nucleus, because the number of protons is matched by the number of electrons in the nucleus, and it is the electrons that determine chemical properties. Nuclei with more than one proton (i.e. not H) also have neutrons, which have no charge. They assist in keeping the positive protons together in the nucleus and are important for stability. Atoms of an element can have different numbers of neutrons, more than one of which can be stable. This variants are called isotopes. They behave the same chemically, but have some different physical characteristics due to size difference.

There are minimum and maximum limits to the number of neutrons that form stable isotopes. Beyond those limits, the atoms tend to decay through radioactivity. For example C-12 and C-13 are stable isotopes. Another natural isotope C-14 is radioactive.

There is also a limit to the number of protons that can be held together by any number of neutrons. Uranium, with 92 protons, has only radioactive isotopes, but U-238 (146 neutrons) decays much more slowly than U-235 (143)or U-234 (142).
