Which object made up of one or more smaller unit objects would make the best model for a group of cells from a plant?
Answers
Answer:
D. Dresser
Explanation:
According to the unified cell theory "all living organism are made of one or more small cells" and new cells arise from one cell through cell division.
From the given examples, the best model for a group of cells from a plant is "dresser" because a cell is consist of small structures called organelles that perform specialized functions likewise a dresser can contain several objects that can act as organelles.
Hence, the correct answer is "D. Dresser".

Explanation:
Answer: Glucose
Explanation: Glycogen is a large, branched polysaccharide that is the main storage form of glucose in animals and humans. Glycogen is as an important energy reservoir; when energy is required by the body, glycogen in broken down to glucose, which then enters the glycolytic or pentose phosphate pathway or is released into the bloodstream. Glycogen is also an important form of glucose storage in fungi and bacteria.

measurements compare?
A. The volume of bromine will be larger in the 100ml beaker.
B. The volume of bromine will be smaller in the 50ml beaker,
C. The volumes will be the same.
D. Both A and B
Answers
The actual volume of bromine in each beaker will be same only the difference in height will be comparable. Therefore, option (C) is correct.
What are the properties of liquid ?A liquid's attributes are;
1) Compared to the volume occupied by a gas, the volume of a liquid is relatively stable at conditions that allow it to remain in the liquid state.
2) A liquid will take the form of the container it is placed in.
3) A liquid's surface in a container must be flat for the attraction forces between its molecules to be in equilibrium both at the liquid's surface and within its body.
Therefore, there will be variations in the measured height of the same volume of bromine in each beaker given that the volume of the bromine is measured in a 50 ml beaker and a 100 ml beaker.

Answers
Answer:
Reflex action/reflex arc/reflex (allow "involuntary") The stimulus (heat) is detected by temperature receptors in the skin. This causes impulses to travel along a sensory neurone to the spinal cord, due to chemical changes across the synapses. Here they go along a relay neurone, and then are sent via a motor neurone to the effector (an arm muscle in this case). The muscle contracts, moving the hand away and preventing further harm.

A biotic factor is a live entity that influences its surroundings. Aquatic plants, fish, amphibians, and algae are all examples of freshwater ecosystems.
Turbulence, temperature, water clarity, habitat size, and water depth all influence the structure and function of ponds and lakes. Temperature interacts to affect lake stratification and water circulation.
Therefore algae that balance the aquatic ecosystem is a major abiotic factor, hence option b in water-growing algae is correct.

OA.
age group
OB. age graph
Oc. age scale
OD
age pyramid
Answers
Answer:
The graphical representation of the age structure is known as age pyramid (option D).
Explanation:
The age pyramid or more properly called population pyramid groups all the individuals of a population, distributing them by age and sex. The name is due to the fact that, in general, the bar graph resembles a pyramid.
The age groups are distributed in the pyramid by age from lowest (bottom) to highest (top), with the sexes forming the sides of the pyramid.
In emerging countries the population is relatively young, which makes the base of the pyramid wide, narrowing as it moves up to the upper age groups.
Age group, age graph or age scale do not correspond to the population graph where the age and sex structure of a population are expressed.

In the laboratory, yeast cells are usually grown at a temperature of 25oC. A scientist wanted to determine if yeast cells would reproduce faster or slower when the temperature was dropped to 15oC. The same number of yeast cells were placed in the same medium with the same amount of nutrients. One sample was kept at 25oC and the other one was kept at 15oC. The number of yeast cells was counted every hour for an eighteen hour period.
Answers
Answer:
This question is incomplete, however, it is asking to identify the following variables:
Independent variable: Temperature
Dependent variable: Number of yeast cells
Constants: same amount of nutrients, same number of yeast cells, same medium
Explanation:
- Independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable effect. In this experiment, the TEMPERATURE at which the yeast are kept is the independent variable.
- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured by the experimenter in the experiment. In this case, The NUMBER OF YEAST CELLS was counted, hence, it is the dependent variable.
- Constants are variables that are kept unchanged or same for all groups by the experimenter in order not to influence the experiment's outcome. In this case, the CONSTANTS are: same amount of nutrients, same number of yeast cells, same medium etc.

The image below shows the cell cycle with checkpoints indicated in red. What will most likely happen if the cell finds a mistake at one of the checkpoints?
Answers
Answer:
I think it may be A. the cell will prevent division from occurring
The most likely to happen if the cell finds a mistake at one of the checkpoints is the cell will prevent the division from occurring. The correct option is A.
What are checkpoints in cell division?Cell cycle checkpoints are processes that monitor the sequence, integrity, and fidelity of the cell cycle's fundamental events. These include cell development to the optimum size, chromosomal replication and integrity, and correct segregation at mitosis.
The cell that divides to produce two daughter cells is known as the mother or parent cell in the process of cell division. Mitosis produces two offspring cells that are genetically identical to the mother cell. The cell cycle has four checkpoints. These are G1, S, G2, and M.
Therefore, the correct option is A. the cell will prevent the division from occurring.

b) cells are the basic structural and organizational unit of life
c) all cells arise from pre-existing cells.

Cross two heterozygous black mice and tell the possible phenotypes and
genotypes in their offspring.
Answers
Answer:
The correct answer is -
Phenotype: 3:1 (dominant black mice: recessive brown allele)
genotype: 1:2:1 (purebred dominant : heterozygous: purebred recessive)
Explanation:
In the given question there is a cross that takes place between two heterozygous black mice. LEt assumes B is black which is the dominant allele and b is the recessive allele or brown. As it is given in heterozygous condition black mice are present which means the B is dominant over b.
Now cross:
Gametes: B and b for each mice
B b
B BB Bb
b Bb bb
By the cross, there are two phenotypic offspring that produce 3 black mice out of four and 1 brown or recessive allele out of four
And, genotypically three offspring in the ratio of 1:2:1 (purebred dominant : heterozygous: purebred recessive)
