C. A mature spore-producing fern plant has fronds and produces
spores
D. A spore grows into a mature gamete-producing plant,
Answer:
the correct answer is D!
A spore grows into a mature gamete-producing plant.
Explanation:
hope this helps :)
A spore grows into a mature gamete producing plant is best describe the life cycle of fern.
What is the life cycle of fern?The life cycle of the fern has two different stages such as sporophyte and gametophyte. The sporophyte stage which releases spores whereas gametophyte stage which releases gametes. Gametophyte plants are haploid whereas sporophyte plants diploid. This type of life cycle is known as alternation of generations.
So we can conclude that a spore grows into a mature gamete producing plant is best describe the life cycle of fern.

Select ALL of the following that are directly involved with making a protein
Ribosome
Cell Membrane
DNA
Cytoplasm
Cell Membranes,Ribosome, Cytoplasm are used to make protein
Explanation:
Proteins are formed in a condensation reaction when amino acid molecules join together and a water molecule is removed. The new bond formed in protein molecules where amino acids have joined (-CONH) is called an amide link or a peptide link.

If 22% of a DNA sample is made up of cytosine, C, what percentage of the sample is made up of adenine,
A?
Answer:
28% of Adenine
Explanation:
Chargaff's Rule states that A = T and C = G
Because of that, the sample must have the equation:
A + C = T + G
G must have the same amount as C so,
A + .22 = T + .22
Both sides of the equation must equal each other by .50, so .50 - .22 = .28
.28 x 100 = 28%
If 22% of a DNA sample is made up of cytosine, C, the percentage of the sample is made up of adenine, A is 28%
What is DNA?The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.

Why does sodium and potassium ions need a protein pump to pass through the cell membrane?
A. The ions have a charge and cannot pass directly through the cell membrane.
B. The ions are moving against the concentration gradient.
C. Energy is needed to move the ions.
D. All of the above.
Cell membrane have been the selective membrane that allows transportation. Sodium and potassium ions need a protein pump as they are charged particles that move against the gradient and need energy. Thus, option D is correct.
What is active transport?Active transport has been the way to move ions and molecules inside and outside the cell membrane. This system of transportation requires energy as the ions move from low concentration regions to the region of the higher electrochemical area.
The sodium and potassium pump needs proteins and energy to move the ions as the inside of the cell is rich in potassium and the exterior is rich in sodium ions. The charged ions moving against the concentration cannot enter the cell without energy and protein pumps.
Therefore, option D. all of the above statements are correct.

Deforestation leads to environmental imbalance. Give reason.
Answer: Well, deforestation is cutting down trees, and many arboreal animals live in those trees. So if they have no proper shelter, they would have no place for personal activities such as breeding, feeding etc. And without those important activities that they have to do everyday, the population of arboreal animals will keep on decreasing until they go extinct. Though that's not the only problem. The herbivores won't get anything to eat, hence not letting the omnivores or carnivores get their food. As you can see, deforestation can create a huge environmental imbalance.
Groundhogs sometimes eat garden vegetables such as these peppers. Once the pepper has been eaten and digested, the seeds exit the animal through its waste. In what way does this help the pepper plants?

Over the next 10 years, many of the UK’s nuclear power stations are expected to close.
Suggest how this may affect the future balance of sources of energy used for electricity production in the UK.
Answer:
Greatly affected.
Explanation:
This closing of nuclear power stations greatly affect the future balance of sources of energy used for electricity production in the UK because the burden of production comes on other sources such as production of electricity from fossil fuels, wind and solar radiation etc. If electricity is produced from fossil fuels so it leads to pollution of the environment whereas if the electricity is produced from wind and solar radiation, it is very costly but good for the environment.

Cause: Earth is surrounded by a magnetic field → Effect: Solar wind deflects toward the poles.
Cause: Solar wind particles interact with Earth’s upper atmosphere → Effect: An aurora is created
Explanation:
I have been able to drag the tiles to the correct boxes to complete the pairs.
When there is a trapping of radioactive solar wind particles in bands by the earth's magnetosphere, it becomes dangerous to travel in space through the Van Allen. Cosmic rays and solar particle add up to the additional hazards that it poses. A Van Allen radiation belt is known to be a zone where energetic charged particles are found. Most of the energetic charged particles originate from the solar wind. The solar wind are captured by and held around a planet by that planet's magnetic field.
When the solar wind interacts with the earth's atmosphere, there is a collision of atoms of oxygen and nitrogen from the earth's atmosphere. The energy that is formed is a colorful glowing halo which is known as an aurora.
Answer:
Cause: Earth’s magnetosphere traps radioactive
solar wind particles in bands around Earth.

what are the two main types of chemical bonds?
Answer:
Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.
Two of the strongest forms of chemical bond are the ionic and the covalent bonds. Chemical bonds form between two atoms, each with its own electron environment.

ionic bonds and covalent bonds.
