Generally, putting one male with two females in a single cage will increase the chances of breeding. To prevent fighting, it's important that there's only one male in each cage. If you're not sure which mice are male, gently lift them up by the tail and look between their legs. Most mice reach sexual maturity (males and females) at 4-7 weeks of age. Younger mice generally produce smaller litters and therefore are not typically mated until they reach 6-8 weeks, of age. Mice that have been housed alone or in same-sex pairs will usually not breed successfully if they are older than 6-8 months.
Which is the MOST accurate description about how the different types of feed mechanisms work.
A. Both positive and negative feedback loops amplify a departure from the set point.
B. Both to negative and positive feedback loop returns to the set point in the reverse direction
C. Positive feedback loops return to the set point in reverse direction, why negative feedback loops amplify the departure from this point.
D. Negative feedback loops return to the set point in reverse,wow positive feedback loops amplify a departure from the set point
Answer:
D
Explanation:
Positive feedback loops are rarer than negative ones because of homeostasis, but they do occur. Negative feedback loops return to the set point in reverse, and positive feedback loops amplify a departure from the set point.

Letter X represents
Inorganic molecules
O organic molecules
O biological catalysts
O simple sugars
Answer: b
Explanation:
All the smaller molecules are made up of the organic elements
The study of a living being is called biology.
The correct answer is B.
The process of conversion of a large molecule into a smaller molecule with the help of an enzyme is called digestion. The enzyme converts the organic and complex molecules to the simpler molecule which helps in absorption and later on is used up to form ATP.
According to the question, the larger molecule which is an organic molecule is breakdown into smaller molecules.
Hence, the correct answer is B that is an organic molecule.

Which is the dark reaction called a cycle
Thank for the points.
Answer:
Photosynthesis consists of two parts. The first requires sunlight and the second does not. The Calvin cycle is also called the dark reactions or light-independent reactions because it's the part that doesn't need energy from the sun to happen. The Calvin cycle takes place within the stroma of the chloroplast.
Why don't lunar eclipses occur during full moons
Answer:
Because the moon's orbit around Earth lies in a slightly different plane than Earth's orbit around the sun, perfect alignment for an eclipse doesn't occur at every full moon. A total lunar eclipse develops over time, typically a couple hours for the whole event.

Explain the role of valence electrons and how they relate to the periodic table of elements?
Plz this i really need to finish this.
Explanation:
The valence electrons determine the group the elements belong in the periodic table. For example, the element sodium, Na, has a valence electron of one and so it belongs to Group 1 in the periodic table. Another example is Aluminium, Al, which has a valence electron of three and therefore it belongs to Group 3 in the periodic table.

How are proteins used in mating by Japanese beetles
A. They build mitochondria from proteins
B. They use proteins to store lysosomes
C. They send proteins as chemical messages
D. They store proteins in the their large vacuoles
Answer:
C. They send proteins as chemical messages
Explanation:
In the case of Japanese beetles, the female is the one who attracts the pheromones that have a role in the mating. The pheromones are the chemicals that serve to get a social response from the same species.
The males, however, produce the protein that helps them discover the pheromones which afterwar is sent to the female with the goal of mating.
the half-cooked egg yolk oozes out only when it is still hot.In the same manner,the magma on the mantle also rises because of high temperature, in the mantle, or the crust?
Answer:
the mantle
Explanation:
The correct answer would be the mantle.
The magma is a hot, molten fluid or semi-fluid located beneath the earth's surface and capable of finding its way through fissures into the surface of the earth in a process known as a volcanic eruption.
From the innermost to the outermost, the earth layer consists of the inner core, the core, the mantle, and the crust. More specifically, the magma is known to originate from the lower part of the crust and the upper part of the mantle. The mantle's temperature is high and forms a layer of partially molten rock.

The central atom in an amino acid that all the groups connect to is a
O A. Hydrogen
.
O B. Oxygen
• O C. Carbon
.
O D. Nitrogen
Answer:
C. Carbon
Explanation:
The central atom in an amino acid that all the groups connect to is a carbon atom.
Amino acids are monomeric units of proteins. They are bifunctional in that they have an amino group and a carboxyl group. These groups are attached to a carbon atom, α-carbon, in a molecule.
This is common to all amino-acids.

In this example, water is an example of which of the following?
Molecules of an element
Molecules of a compound
Atoms of a compound
A mixture
Answer:
B
Explanation:
i took the test
The correct option is (B). Molecules of a compound.
What do you mean by molecules?A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion.
Moreover, molecules are made up of one or more atoms. If they contain more than one atom, the atoms can be the same (an oxygen molecule has two oxygen atoms) or different (a water molecule has two hydrogen atoms and one oxygen atom). Biological molecules, such as proteins and DNA, can be made up of many thousands of atoms.
Hence, the smallest particle of any substance which can exist independently and retain the physical and chemical properties of the substance, made up of one or different elements is a molecule.

Organisms that live in the rainforest have developed unique adaptations that aid in their survival. Which adaptation would most likely be found in organisms living in the rainforest? a. herbivores feed on low-lying plants b. birds have beaks adapted to break open hard shells c. insects have a widely-varied diet d. plants are able to store water in their leaves Please select the best answer from the choices provided A B C D
Answer:
Your answer is most probably A). B) implies that nuts are the only thing for birds to eat in a rainforest, which doesn't make sense, C) implies that the insects would need a widely-varied diet to survive, but again there's an abundance of things that a hungry bug can eat, so they don't need a wide dietary coverage, D) suggests that there may be droughts in the area for which the plant may need to be prepared, but in the RAINforest droughts are uncommon.

A mutation in the upland cotton plant causes the development of
chloroplasts with a single outer membrane and no internal membranes.
Which of the following would most likely be observed in chloroplasts of
cotton plants with this mutation?*
Answer:
This question is incomplete as it lacks options. The options are:
A) They would be unable to remove waste products because internal transport proteins would not be present
B) They would be unable to generate ATP and NADPH needed to make sugars because these processes occur on membranes within the chloroplast
C) They would be unable to take up carbon dioxide because CO2 is transported into the chloroplast in membrane-bound vesicles.
D) They would be unable to move within the cell because only organelles with double membranes are mobile.
The answer is B
Explanation:
Chloroplast is an organelle within the cells of certain organisms including plants. It is the site of photosynthesis in autotrophic organisms i.e. organisms capable of making their own food. The chloroplast is double-membraned, like most eukaryotic organelle, made up of inner and outer membrane.
The membranes of the chloroplast contains structures such as thylakoid, where the light dependent reactions of photosynthesis that produces ATP and NADPH needed to produce sugars, take place. Hence, a mutation in the upland cotton plant that causes the development of chloroplasts with a single outer membrane and no internal membranes will make the chloroplasts of this cotton plant be unable to generate ATP and NADPH needed to make sugars because these processes occur on membranes within the chloroplast.
can a cell can survive even if the process to produce ATP is disrupted?
Answer:
No, because ATP provides energy for cells in order for them to carry out their functions. If disrupted it will cause the transport chain to stop which causes ATP to stop and the cells can no longer carry out their functions and will die.
