Answer:
It would depend if it's sexual reproduction or asexual reproduction, if it's asexual then it would be almost exactly identical but if it were sexual then it would be quite different as it would be using dna from both parents.
Explanation:
A force of 240 N causes an object to accelerate at 3.2 m/s2. What is the mass of the object?
A.75N
B.75 kg
C.0.013 kg
D.768 kg
Which is the answer?
Answer:
B.75 kg
Explanation:
Given parameters:
Force on the object = 240N
Acceleration of the object = 3.2m/s²
Unknown:
Mass of the object = ?
Solution:
Force is the pull or push on an object. According to Newton's first law; it is mathematically expressed as;
Force = mass x acceleration
The unknown here is the mass, simply input the parameters and solve for it;
240 = mass x 3.2
mass = [tex]\frac{240}{3.2}[/tex] = 75kg
The mass of the object is 75kg

Patients with a specific medical condition have been provided with a new device that helps them manage their condition. The patients will be required to participate in a survey regarding the usefulness of the device. How can the manufacturer be certain that no bias enters into the surveys? Group of answer choices
Answer:
by providing a toll-free number in case there are questions about the devices.
Explanation:
One of the best ways to make certain that this does not happen is by providing a toll-free number in case there are questions about the devices. Doing so makes sure that the customers are fully aware and understand the device and what it is doing. This prevents the customer from assimilating other benefits that they may experience which have nothing to do with the provided device into the survey and potentially contaminating the data with false feedback.
What is a buffer? Why is it useful to cells?
Buffer are defined as substances that maintain a constant range of pH by the addition of the base and acid. It is important for cells to maintain the osmotic pressure and pH in the cell environment.
What is the importance of a buffer?In biology, the buffer has been the substances that are organic in nature and are used for regulating and controlling the level of the acids and bases that alters the pH of the system. It plays a crucial role in cells.
It is important for the cell to have a buffer solution, like bicarbonate ions in the blood that maintains the pH and the concentration of the hydrogen and hydroxide ions. It provides regulation of the osmotic balance and maintains the internal environment condition of the cell.
Therefore, the buffer is important for cells.

Which of the following statements is supported by the principles of cell theory?
I. Certain cells can form on their own, without requiring a parent cell.
II. Genetic information is passed from a parent cell to a daughter cell.
III. The basic units of all living things are organelles.
Answer:
the statement that is correct is the lll.
The statement which is supported by the principles of cell theory is as follows:
Genetic information is passed from a parent cell to a daughter cell.Thus, the correct option for this question is B.
What is Cell theory?Cell theory was proposed by two famous scientists known as M.J. Schleiden and T. Schwann. The principles of cell theory are as follows:
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.A Cell is the structural and functional unit of organisms.This cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from a pre-existing cell. A Virus is an exception to the cell theory.
Originally, none of the given statements exactly matches any one of the three principles of cell theory. But the second option reached approximately near around it.
Therefore, the correct option for this question is B.

Are dangerous and should be removed.
Are fully functional structures in a species.
Are usually present, but are no longer functional.
Have been completely eliminated from the species.
Answer:
Are usually present, but are no longer functional.
Explanation:
Vestigial structures are "evolutionary remnants". They are anatomical features that were once important throughout the organism's evolution, but now have no function. However, they aren't harmful either, so there has been no selective pressure for them to be removed via evolution.
Good examples in humans are the tail bone, wisdom teeth, and the appendix.

on the object, and how does the net force change the motion of the object?
Answer:
The force is by putting the two same objects on both sides and the motion is the scale
The force is by putting the two same objects on both sides and the motion is the scale.
What do you mean by force?In physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull.
The normal force acts in a direction normal to the surface interaction between objects. Friction is a force that opposes motion on surfaces. Other examples of non-fundamental forces include the elastic force, tension.
Force is the fundamental result of an interaction between two objects, while power is an expression of energy consumed over time (work), of which force is an element.

when you cut a stem a watery liquid will come out. why?
When offspring produced by sexual reproduction move into different environments, new species sometimes emerge over time. Which characteristic of sexual reproduction allows this result to occur?
A) speed with which offspring are produced
B) number of offspring produced
C) diversity of the offspring produced
D) size of the offspring produced
Answer:
c) diversity of the offspring produced.
Explanation:
Because sexual reproduction involves gametes (sex cells with only half the number of chromosomes), each offspring produced is genetically unique (as they get a random selection of chromosomes from both parents). This allows mutations to occur, which may be beneficial (or not) in the environment. Over time, the offspring that have the favourable characteristics will survive more easily to reproduce, whereas those with less helpful characteristics will not. This means that the favourable characteristics will be passed on to the next generation, while the less favourable ones will not be time. If this occurs for many generations, a new species may emerge.
In a block and tackle system each pulley that you add will all the force to be ____.
1. decreased
2. increased
Answer:decreased
Explanation:
Answer:
Decreased
Explanation:
When you add extra pulleys, the minimum force that is needed to be given off by the person pulling lowers. For example if you have one pulley and pull on it, you require more force to move the object than your friend with two pulleys. He requires half the force that you do to move the object.
