Answer:
Protista is a kingdom or large grouping that comprises mostly single-celled organisms such as the protozoa, simple algae and fungi, slime moulds, and (formerly) the bacteria. They are now divided among up to thirty phyla, and some have both plant and animal characteristics.
Why isn’t color a very useful property in identifying a mineral?
Answer:
Generally, color alone is not the best tool in identification because color can be highly variable. Some minerals can occur in a variety of different colors due to impurities in the chemical makeup of the mineral.

membrane molecules that use the energy of atp to move ions against a concentration gradient are called
Membrane molecules that use the energy of ATP to move ions against a concentration gradient are called PUMPS. This type of transport is called active transport.
Active transport is a type of transport that requires energy (e.g, ATP) to move molecules and/or ions against a concentration gradient.
In active transport, specific membrane transporter proteins referred to as pumps are used to move ions against an electrochemical gradient across biological membranes.
These protein pumps are fundamental for creating electrochemical gradients that are subsequently used by cells for diverse purposes (e.g., muscle contraction).

Explain why the sperm cells differ from other cells in the male
sperms are gametes (reproductive cells) which have half the number of chromosomes (22 autosomes +1 sex chromosome) .Those cells have 23 chromosomes only as their nucleuse fuses *during fertilization* with the ovum's nucleuse which has 23 chromosomes as well . Also it has a special structure which makes it adapted for movement since it's a mobile cell

An environmental factor such as storms and extreme heat or cold that affects
population regardless of their density
Answer:
density-independent factor
Explanation:
density-independent factor, also called limiting factor, in ecology, any force that affects the size of a population of living things regardless of the density of the population (the number of individuals per unit area).
hope this helped!!!! have a great day!
An environmental factor such as storms and extreme heat or cold that affects population regardless of their density are known as density- independent factors.
What are density- independent factor?Density- independent factors are type of limitation factors that affects the population size in specific environment regardless of the density of that population.
Density of population can be defined as number of individuals per unit area.
Here storms and extreme heat are the limiting factors that reduces the population size regardless pf their density.

You are attempting to carry out a transposon mutagenesis experiment using the pRL27 system. The Donor strain you use was giving to you by a lab mate who has been culturing it continuously for several months. When you set up your control plates, you find that the Donor strain grows poorly on Luria DAP Agar. Your transformation efficiency is very poor for this attempt at mutageneis. What likely happened to the Donor strain
The most likely happened to the donor strain is that the transposon is active in the donor resulting in the gradual accumulation of mutations. The accumulation of mutations is promoted by the insertion of the transposon.
A donor strain is a bacterial strain that contains a mobilizable fragment of DNA called plasmid.
These strains (donor strains) exploit the transference properties of a conjugative plasmid to modify a particular recipient strain.
Transposons, also known as jumping genes, are mobile genetic elements that alter the genome of an organism by jumping and thus inserting them into genetic sequences (i.e., into protein-coding sequences).
In this case, the presence of a transposon in the donor strain affected the expression of many genes required for the donor strain in order to grow into Luria DAP Agar.

Which of these solutions is the best way to help a city as its population grows
and its air becomes more polluted?
O A. Invest in urban sprawl to better disperse the pollution.
OB. Invest in alternative energy sources to reduce emissions.
O C. Reduce road construction to dissuade new residents.
O D. Reduce air-quality regulations so businesses can grow unimpeded.
Answer:
B. Invest in alternative energy sources to reduce emissions.
Explanation:
The best way to help a city as its population grows, and its air becomes more polluted, is to invest in alternative energy sources to reduce emissions. The correct option is B.
What is pollution?Pollutants are the name for these dangerous substances. Natural pollutants include volcanic ash, for example. They can also be brought by human activities, such as factory runoff or waste.
Air pollution is caused by solid, liquid, and gaseous pollutants. These gases and particles can be produced by factories, volcanoes, wildfires, dust, pollen, and vehicle and truck emissions.
To stop pollution, we must use alternative energies that do not cause pollution.
Thus, the correct option is B. Invest in alternative energy sources to reduce emissions.

A-Level Environmental Science exam question:
Since the 1950s, the exploitation of the rare-earth elements has increased from a few tonnes per year to over 150 000t per year. They are used in a wide range of applications, including new developments in transport, electronics and healthcare.
Although the main metals used following the industrial revolution are still important, economic development since the mid 1900s has involved the use of relatively small quantities of a much wider range of metals.
Many rare-earth elements have a relatively high mean crustal abundance, but they rarely occur in locally concentrated deposits.
Figure 1.1 shows details of the reserves and production of rare-earth elements in seven countries.

What are the most important benefits trees and fruit-bearing trees?
Answer:
Trees give off oxygen that we need to breathe. Trees reduce the amount of storm water runoff, which reduces erosion and pollution in our waterways and may reduce the effects of flooding. Many species of wildlife depend on trees for habitat. Trees provide food, protection, and homes for many birds and mammals.

where do photosynthetic organisms get the energy needed to make sugars during the light-independent/dark reactions?
Answer:
They use the glucose they have stored from previous photosynthesis reactions.
Explanation:
The dark reaction takes place external to the thylakoids. The energy from ATP and NADPH is used in this process to fix carbon dioxide (CO2).
What is light-independent/dark reactions?Carbon fixation, reduction, and regeneration are the three stages that make up the Calvin cycle, which is another term for the dark reactions that take place during photosynthesis.
The stroma of the chloroplast is the location where the light-independent process, also known as dark reactions or the Calvin-Benson cycle, is carried out. Carbon-based molecules are formed through a chain of chemical events that begin with carbon dioxide. The production of ATP and NADPH during the light-dependent process supplies these processes with the energy they need to proceed.

Answer:
Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula.
Explanation:
Answer:
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. In a chemical change, the kind of matter changes, and at least one new substance with new properties is formed.
Explanation:
Physical changes are limited to changes that result in a difference in the display without changing the composition.

Answer:
The correct answer is C (The change of color allowed them to hide better from predators)
Explanation:
Before, the deer mice were easy prey for predators since their color stood out and the predators could find them. Therefore, the change of color allowed them to hide better from predators. You may be tempted to answer a, but if you read carefully it says "The change of color camouflaged them, which helped them HUNT better." Clearly A is wrong since deer mice don't really hunt.
