a _ is a push or a pull on an object
Answer:
Force
Explanation:
Answer:
A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction.

How does a mouse reproduce ?
Answer:
Mice are breeding machines. They have a gestating period of 19 to 21 days. A female mouse gets pregnant about 5 to 10 times each year and can give birth to a litter of 3 to 15 pups. On average, a female mouse atleast give birth to 35 to 56 pups. The mice reproduce each year, and the mother can mate immediately after giving birth.
2. Your teacher instructed you to measure the salinity of brine you will use in
curing fish. Which of these will you do?
a.
Recall and master the procedure in using a salinometer
b. Review and master the procedure in using the thermometer
c. Review the procedure in using a psychrometer
d. Review the procedure in using a refractometer
Answer:
a. Recall and master the procedure in using a salinometer
Explanation:
Salinometer, which is also known as salimeter is a laboratory equipment used to measure the salinity of a solution. Salinity refers to the concentration/amount of salt in a solution.
According to this question, a student was instructed by his/her teacher to measure the salinity of brine used in curing fish. This means that to do this, the student will have to make use of a SALINOMETER. In order to use the salinometer, the student has to recall and master the procedure in using a salinometer.
Which is NOT a function of proteins?
(Choose only ONE answer.)
1)working in the immune system
2)providing energy
3)working as enzymes
4)building muscle
Answer:
1. working in the immune system.
Explanation:
Proteins are responsible for the development of hairs, skin, wool, and nails in our body. Meat, eggs, and fish are some of the rich food sources of proteins. Enzymes are proteins made up of amino acids and acts as biological catalysts in our body. However, glucose serves the purpose of energy provider for the metabolism which is not a protein.
A fruit fly somatic cell contains 8 chromosomes. How many chromosomes will each fruit fly gamete contain?
Answer:
The somatic cells of fruit flies contain eight chromosomes, which means they have two sets of four chromosomes. Meiosis is the process by which sex cells are produced. Sex cells are haploid, which means they have one set of chromosomes.
Explanation:
Fruit flies have two sets of four chromosomes because their somatic cells have eight chromosomes. The process through which sex cells are created is called meiosis. The haploid nature of sexual cells means that they only have one set of chromosomes.
What is Meiosis?In sexually reproducing organisms, meiosis is a unique type of cell division of spermatids that results in the production of gametes, such as sperm or egg cells. Two rounds of division are necessary, and the end product is four cells with just one duplicate of each chromosome.
When the chromosome count in daughter cells is decreased to half that of the parent cell during meiosis, the process is known as reduction division. For instance, while a human cell has 46 chromosomes, the egg and sperm cells created by meiotic division only have 23. In the above given example, fruit flies have two sets of four chromosomes as their somatic cells have eight chromosomes.
Thus, fruit flies have two sets of four chromosomes because their somatic cells have eight chromosomes.

Use the picture to explain how CONVECTION heat transfers could be responsible for the weather in our atmosphere.
Answer the question in 2-3 complete sentences.
Answer:
The sun's waves heat the ground, causing it to warm (radiation). The energy flows from the warmer ground to the cooler air (conduction), causing it to rise (convection). When the rising air reaches a certain point, it expands, cools, and the cooler expanded air can no longer hold as much water vapor so it rains.

How does the operator region of DNA work to regulate gene expression?
Answer:
Explanation:
Operator region are region of DNA (deoxyribonucliec acid) that repressors protein binds to prevent transcription.
Repressor is an example of regulatory protein they regulate the rate at which transcription of operon occurs . A repressor functions when its bounded to the operator and it prevent enzyme RNA (ribonucliec acid)polymerase from moving to DNA to transcribe the nitrogenous bases by placing a complementary base pair.
Activators are other regulatory proteins that bounds to its DNA binding site and increases transcription of the operon.

In the female human reproductive system, eggs are created in an ovary, and implanted in the uterus. For the embryo to grow, it must receive nutrients and oxygen. This problem is solved through an organ called the A. Amniotic sac B. Placenta C. Uterus D. Umbilical cord
Answer:
The correct answer is D. Umbilical cord
Explanation:
The umbilical cord connects the fetus to the placenta and through it exchanges nutritional substances as well as oxygen-rich blood. The umbilical cord is maintained throughout gestation until the moment of birth, when it is cut and leaves a permanent scar, the navel. The umbilical cord is responsible for breathing and feeding the fetus until the moment it is born, so any failure or blockage in the circulation of oxygen and nutrients through the cord can lead to injury or even death of the embryo. It also serves to remove waste and carbon dioxide (CO2).

Suppose if all the bones of the skull (facial bones) are fused together, which function would you not be able to carry out?
Answer:
to masticate food
Explanation:
In adults, all the bones of the skull, except one, are fused together by immovable joints referred to as sutures. The sutures are fibrous joints which hold the bones of the skull together to form a rigid and strong structure that protects the brain. Skull bones fuse around two-years (18 to 24 months after birth). The only skull bone that is not fused by sutures in adults is the mandible, which is used to masticate food.
