Answer: PLEASE MARK ME AS BRAINLIST
Explanation:
The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells (cork) as it appeared under the microscope.

Sample Response: When there is less rainfall, land,
which is part of the geosphere, becomes dry. When there
is not enough water, plants will not get the nutrients they
need from the soil and animals will not get enough water,
and they will die. Both plants and animals are part of the
biosphere. Less precipitation would also mean less water
in lakes and groundwater, parts of the hydrosphere, and
less evaporation. The atmosphere may also be affected
due to less water vapor.

When there is less or no rain than expected it will lead to draughts.
Draughts:When there is less rainfall all the parts and organisms of the earth get affected. Water is an essential component of life. Less rainfall leads to the scarcity of water on the earth.
Farmers will not get enough amount of water for farming, groundwater levels also get affected. Plant and animal life also gets affected, and this affects the survival of organisms. Draughts can also affect the amount of water in the hydrosphere.
Food, fruits, and vegetables also get reduced because of less amount of rainfall. Therefore good rain is essential for the lives of the plants and animals. This is important for the survival and the good life of the organism.
Therefore, When there is less or no rain than expected it will lead to draughts.

Explain in your own words an atom and an element.
Answer:
Explain in your own words an atom and an element.
Explanation:
A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.
Which of the following does NOT describe a protein function? A. Enzyme B. Short-term energy C. Antibody D. Endorphin
Answer:
B. Short-term energy
Explanation:
A, C, and D are all protein functions.
B is characteristic of carbohydrates.
Proteins are the macromolecules that act as enzymes, antibodies, and endorphins. It does not act as short-term energy. Thus, option B has been correct.
What are proteins?Proteins are polymers that are large molecules and are essential for several bodily activities, including immune reactions, hormone synthesis, growth, development, energy, and enzyme activities.
Enzymes are made of proteins that speed the biochemical reactions, antibodies are made of proteins that are immunoglobulins and act as a defense for the body. Endorphins are the hormones that are synthesized in stress and painful conditions.
Proteins just do not provide short-term energy but provide energy that can suffice for a longer period of time so that it can perform the various functions and activities in the cell.
Therefore, option B. proteins are not short-term energy.

A. Osmolarity
B. Equilibrium
C. Homeostasis
D. Tonicty
The osmotic gradient, which is the concentration difference between two solutions on either side of a semipermeable membrane, is used to determine a particle's concentration in a solution. Thus, Option A is correct.
What is osmolarity of a solution?Osmolarity, which is determined by the number of osmosis of a solute per liter of solution, is a gauge of solute concentration.
According to their relative osmolarity, solutions can be broadly characterized as hypertonic, hypotonic, or isotonic.
Osmolarity is important because cells cannot survive if their environment's osmolarity is significantly different from their own.
From a lower osmolarity to a greater osmolarity, water flows over a membrane. It switches from the diluted to the concentrated side, to put it another way.
Therefore, osmolarity measurement of the pressure gradient of two solutions that are separated by a selectively permeable membrane.

Explanation:
When adding more sucrose to a 0.7 M sucrose solution, why does it not dissolve as readily as it did at a lower molarity? a) the ions in the solution interact with the sugar and that interferes with its solubility b) the solubility of the solute depends on wether the solute has hydroxyl functional groups or not c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules d) hydrogen bonds in the water molecules change the electrical charge of the sugar molecule, which prevents it from dissolving further in the water
Answer:
The correct answer is option c.he solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules
Explanation:
The Solution contains a solute (sucrose for this situation) and dissolvable (water for this situation). A saturation or unsaturation of a solution relying upon whether it can even now dissolve a solute or not.
As indicated by this inquiry, the sucrose solution is saturated as the 0.7 M sucrose arrangement doesn't disintegrate the sucrose (solute) anymore. The immersion of the sucrose arrangement happens in light of the fact that the measure of solutes is likening the number of solvents in the solution. The solubility of a particular solution relies on saturation.

How is DNA expression regulated in individual cells?
Answer:
Gene regulation can occur at any point during gene expression, but most commonly occurs at the level of transcription (when the information in a gene's DNA is transferred to mRNA). Signals from the environment or from other cells activate proteins called transcription factors.
Explanation:
Gene regulation can take place at any stage of gene expression, although it often happens during transcription when the data from a gene's DNA is converted to mRNA.
What is gene regulation?Proteins known as transcription factors are activated by signals from the environment or from other cells.
Limiting the amount of mRNA that is generated from a certain gene regulates transcription.
Eukaryotic gene expression is regulated by the nucleus-based mechanisms of transcription and RNA processing and the cytoplasm-based activities of protein translation.
Therefore, the translation of mRNA into proteins is regulated by post-transcriptional processes, which constitute the second level of regulation.

Atoms connected by covalent bonds share a ionic compounds. b pairs of electrons. c carbon and oxygen. d hydrogen ions.
Answer:
B
Explanation:
Atoms connected by covalent bonds share electrons. Therefore, the correct answer is option B.
Extremely high ionization energies prevent some elements from accepting electrons, and extremely low electron affinities prevent some elements from accepting them. These elements' atoms frequently share their electrons with those of other elements or with other atoms of the same element in order for both atoms to achieve stability by forming an octet configuration in their respective valence shells. Covalent bonds are those associations that involve sharing electron pairs between entities of different or similar kinds.
Therefore, a pair of electrons is shared between atoms connected by a covalent bond. The correct answer is option b i.e. pairs of electrons.
