Answer:
Scientists first discovered chromosomes in the nineteenth century, when they were gazing at cells through light microscopes. But how did they figure out what chromosomes do? And how did they link chromosomes — and the specific genes within them — to the concept of inheritance? After a long period of observational studies through microscopes, several experiments with fruit flies provided the first evidence.
what is cell cycle? in detail
Answer:
A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

What is a bacterium?what are the process it does? (all the process from beginning to the end)
Answer:
below
Explanation:
Bacterium or bacteria is a unicellular/prokaryotic microorganism that is present in many different settings. I'm not really sure what you mean by "process" but I assume it is how bacteria reproduce. In short, the parent cell creates two clone daughter cells. This procress is called binary fission.

He determined the ratio of mass to charge for electrons.
He determined the amount of charge on an electron.
Answer:
Explanation:
He determined the amount of charge on an electron
Explanation:
He determined the amount of charge on an electron
The information which Millikan contributed to the understanding of electrons is: D. He determined the amount of charge on an electron.
An atom can be defined as the smallest unit which comprises the matter that forms all chemical elements. Thus, atoms are typically the fundamental building blocks of matter and as such determines (defines) the structure of a chemical element.
Generally, atoms are typically made up of three (3) distinct particles and these are;
Protons.Neutrons.Electrons.Electrons can be defined as the subatomic particles of a chemical element that are negatively charged and as such are having a magnitude of -1.
Robert Andrew Millikan was born on the 22nd of March, 1868 in Illinois, United States of America. He was an experimental physicist who got honored with a Nobel Prize in 1923 for his outstanding work in the field of physics, which included the following;
The study of the photoelectric effect.The measurement of the elementary electronic charge of a single electron.This ultimately implies that, Robert Andrew Millikan using an electric field with a small oil-drop determined the magnitude of an electron's charge.
In conclusion, the information which Millikan contributed to the understanding of electrons is determining the amount of charge on an electron.

What organelles are present in both plant and animal cells?
Answer:
Explanation:
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
Answer:
because they both contain eukrayotic cells.

Fitness in an evolutionary sense is measured in:
a. Number of viable offspring produced
b. Physical appearance
c. Lifespan
d. Ability to survive
Answer:
D. ability to survive
"The central concept of natural selection is the evolutionary fitness of an organism. Fitness is measured by an organism's ability to survive and reproduce, which determines the size of its genetic contribution to the next generation."
Fitness in an evolutionary sense is measured in the ability to survive in a particular habitat. Thus, the correct option is D.
What is Fitness?Fitness may be defined as the situation of survivability of an organism under a given condition.
It is the concept of natural selection that it is only the relative fitness that estimates the existence or extinction of species in a particular habitat.
The Relative fitness of an organism overall depends on relative survival and relative reproduction.
Therefore, Fitness in an evolutionary sense is measured in the ability to survive in a particular habitat. Thus, the correct option is D.

How many valves does the human heart have?
Answer:
The right auricle opens into the right ventricle, this opening is guarded by the tricuspid valve (having three cusps or flaps). Similarly, the opening between the left auricle and the left ventricle is guarded by the bicuspid valve (having two cusps or flaps). These valves regulate the flow of blood in one direction i.e., from auricles into the ventricles.
The blood flows from the right ventricle into the pulmonary artery and from the left ventricle into the aorta (the largest artery). The flow of blood from the ventricles into these two arteries is also regulated by valves. These valves resemble a half moon, hence they are called semi-lunar valves. These valves are present at the opening where the pulmonary artery and aorta leave the right and left ventricles respectively. They ensure that the blood does not flow back into the ventricles.

How does the environment influence the survival advantage/disadvantage of certain characteristics?
Answer:
Many students believe that the physical characteristics of organisms change in response to changes in the environment in which the organisms live, and that these changes are passed on to future generations. For example, there is widespread belief that, over many generations, giraffes have gradually developed longer necks as they competed with other animals and each other to reach higher and higher leaves on trees for food.
Many students also believe that organisms can deliberately develop new traits in order to improve their chances of survival. As an example, students believe that moths with spotted wings are able to change the color and patterns on their wings so they are better camouflaged among tree trunks that may have become darker from pollution from industry. Many students also believe that repeated use of insecticides like DDT has meant present populations of insects have become

What is the definition of Eyewitness
You are conducting an experiment to measure the gain in mass of a young mouse over 10 weeks. Instructing a graph represent your data which variable should you place along the X axis and which variable should you played along the Y axis
In this experiment, the gain in mass should be plotted along the Y axis while the time (in weeks) should be plotted along the X axis of the graph.
The easiest pattern of reporting experimental results in science is by the use of a graph. A graph is a diagrammatic representation of the relationship between two variables along the X-Y Cartesian axes.
In this experiment, we are trying to represent the relationship between the gain in mass and time taken. The experiment is scheduled to run over a course of ten weeks.
The X axis ought to represent the time in weeks while the Y axis ought to represent the gain in mass.
This derives from the fact that it is conventional for the dependent variable (in this case gain in mass) to be plotted along the Y axis while the independent variable (time) to be plotted along the X axis.

A football player gets tackled during the game, which of the following body systems is responsible for protecting their organs?
circulatory system
reproductive system
skeletal system
nervous system
Answer:
Skeletal system
Explanation:
the bones of the skeleton protect the internal organs and reduce the risk of injury on impact. For example, the cranium protects the brain, the ribs offer protection to the heart and lungs, the vertebrae protect the spinal cord and the pelvis offers protection to the sensitive reproductive organs.
Answer:
I believe your best choice from the given choices above would be C) skeletal system. The bone structure within the human body, such as the rib cage for instance, provides protection for our organs and takes more impact rather than any of our organs. Without our skeletal system, we would have zero protection for our organs, increasing the chance of more internal body damage.
