Root cells of plants take in some minerals from the surrounding soil by spending energy. After the plant obtains enough minerals to maintain health, the plant will continue to absorb minerals from the soil. Which reason best explains why root cells need to spend energy in order to transport some minerals into cells?
The question is incomplete; the complete question is;
Root cells of plants take in some minerals from the surrounding soil by spending energy. After the plant obtains enough minerals to maintain health, the plant will continue to absorb minerals from the soil. Which reason best explains why root cells need to spend energy in order to transport some minerals into cells?
Root cells are unable to use sunlight energy for mineral uptake.
Mineral concentration is higher in root cells than in the surrounding soil
Cell membrane pores in roots are too small for passive uptake of minerals
Cell membranes in roots lack proteins for the passage of minerals.
Answer:
Mineral concentration is higher in root cells than in the surrounding soil
Explanation:
Mineral uptake by plant roots occurs by active transport of ions into the cells of root hairs, this process requires energy.
The concentration of minerals in the soil is quite low. The root hair cells of plants possess carrier proteins that carry mineral ions and move them into the cell against existing concentration gradient. This process requires energy and is known as active transport.
Why does the cell membrane need proteins embedded in it?
Answer:
Transporter or Carrier Proteins. They are embedded in the cell membrane to help transport glucose and amino acids across the membrane. They are too large to go through ion channels.

What is the complementary DNA strand TAC GGC CGT TAT
Answer:
1a. The template DNA strand, from which the mRNA is synthesized, is 5’ CAAACTACCCTGGGTTGCCAT 3’
(RNA synthesis proceeds in a 5’ à 3’ direction, so the template strand and the mRNA will be complementary to each other)
b. The coding DNA strand, which is complementary to the template strand, is 5’ ATGGCAACCCAGGGTAGTTTG 3’
c. The sequence of the mRNA is 5’ AUGGCAACCCAGGGUAGUUUG 3’
(the sequence of the mRNA is complementary to the template strand and identical to the coding strand with U substituted for T)
d. The third codon is 5’ ACC 3’. Therefore, the corresponding anti-codon is 5’ GGU 3’
True or False: Glycogen, Starch, and Cellulose are all polysaccharides.

why are there mosquitos
Answer:
To balance the food chain.
Explanation:
Mosquitoes actually play a big part in the food chain.. Animals such as frogs eat them, and what if other foods that frogs eat go out(Not saying it's gonna happen, its just a what-if)? They will have to resort to the mosquitoes. And if those were gone, the frogs would go out. Then a certain number of animals maybe maybe not would have to develop a new diet due to the extinction of frogs.
Answer:
i have no clue. i hate mosquitos.

PLEASE HELP!!!!!!!!!!!!!!!!!!!! WHAT IS THE CONTROL GROUP FOR THIS
Hypothesis:
In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.
If predators are increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
If pollution is increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
If the amount of food available is increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
Procedure:
The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable), outcome variable (dependent variable), and control group for this experiment.
Reminder: The test variable is the item that is changing in this investigation. The outcome variable is the item that you are measuring in this investigation. The control group is the group in the experiment where the factors being tested are not applied. It allows scientists to set a baseline to compare the experimental groups that do have factors applied to them.
Test variable (independent variable): Limiting factor- Food, Pollution, Predators.
Outcome variable (dependent variable): Cricket Frog (population)
Control group:
Answer:
decrease
decrease
increase
control group is the cricket frog population
Explanation:
Its the group that is being measured.
Answer:
Limiting factor- Food, Pollution, Predators.
Outcome variable (dependent variable): Cricket Frog (population)
Control group: Cricket Frogs in the Florida Everglades without changes in or manipulation of the population.

Identify the macromolecule in the figure that store genetic information in molecules DNA, and RNA?
Answer:
The correct answer is - option 2. (chemical structure of the nucleotide)
Explanation:
Nucleic acid, DNA and RNA stores genetic information which helps in produces various proteins and for the next generation of the cells. Nucleic acids are made up of monomers of nucleotides joined together to form the nucleic acids. Each nucleotide has sugar, a nitrogenous base, and phosphate in the structure that joined to form a helix structure.
Thus, the correct answer is - option 2.
Answer:
Explanation:

In scientific notation, a number is expressed as a value between 1 and 10
multiplied by a power of 10 *
True or false
The answer is true
Explanation:
The definition of scientific notation is: The method of writing very large or small numbers as a product of a number greater than or equal to 1 and less than 10 multiplied by a power of 10
Hope this helped!
The given statement about scientific notation is true which states that in scientific notation, a number is expressed as a value between 1 and 10 multiplied by a power of 10 .
What is scientific notation?Scientific notation is defined as a way of expressing numbers which are too large or too small so that they can be easily written in decimal form. It can be referred to the scientific form or the scientific index form or even the standard form.
Base ten notation is used by scientists, engineers as it helps in simplification of arithmetic operations. It contains the significant figures which include all non-zero numbers , the zeroes between significant digits and zeroes which are needed to be significant.
In scientific notation, the base should always be ten. The exponent should be a non-zero integer and it can be either positive or negative.

Why do globes lean sideways?
A.To allow them to spin easier
B.To demonstrate gravity
C.To demonstrate the passing of the seasons
D.To demonstrate the tilt of the Earth's axis
Answer:
D
Explanation:
Globes lean sideways To demonstrate the tilt of the Earth's axis. Option D is correct.
Globes lean sideways to demonstrate the tilt of the Earth's axis. The Earth is tilted on its axis by about 23.5 degrees. This tilt is what causes the changing seasons on Earth.
When a globe is tilted, it helps us visualize how different parts of the Earth receive different amounts of sunlight at different times of the year. For example, during the summer in the northern hemisphere, the North Pole is tilted towards the Sun, so it receives more direct sunlight and experiences warmer temperatures. At the same time, the South Pole is tilted away from the Sun, receiving less direct sunlight and experiencing winter.
By showing the tilt of the Earth's axis, globes help us understand why we have seasons and why they occur at different times in different parts of the world.
To summarize, globes lean sideways to demonstrate the tilt of the Earth's axis, which helps us understand the changing seasons on Earth. Option D is correct.

Answer:
Light Independent Reactions
Explanation:
The stroma is the fluid-filled space of chloroplasts the thylakoids. It contains all the enzymes required for light-independent reactions of photosynthesis and is, therefore, the site of the Calvin cycle.
The Krebs cycle and glycolysis are stages of cellular respiration and occur in the mitochondria.
The light-dependent reactions occur in the thylakoids
