Sex chromosomes are the gene that decides on our gender. The males have X and Y sex chromosomes (XY). Females have only two X sex chromosomes (XX).
More info: Because males have both X and Y sex chromosomes, their genes decide the offspring's gender.
Answer:
The sex chromosomes are referred to as X and Y, and their combination determines a person's sex. Typically, human females have two X chromosomes while males possess an XY pairing. This XY sex-determination system is found in most mammals as well as some reptiles and plants

Lenny accidentally drops his matchbox car into a graduated cylinder. The car has a mass of 10 grams and the water level in the cylinder rises from 41 ml to 46 ml. Determine the density of the matchbox car. The formula for density is D =
m
v
.
A) 0.5 g/ml
B) 2 g/ml
C) 15 g/ml
D) 50 g/ml
Answer:
B) = 2 g/mL
Explanation:
Given data:
Mass of car = 10 g
Volume of water = 41 mL
Volume of water+ car = 46 mL
Density of car = ?
Solution:
Density is equal to the mass of object divided by volume of object.
Formula:
d = m/v
volume of car = Volume of water+ car - Volume of water
volume of car = 46 mL - 41 mL
volume of car = 5 mL
d = 10 g/ 5 mL
d = 2 g/mL

why virus is imortal?
Answer:
Strictly speaking, viruses can't die, for the simple reason that they aren't alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can't thrive independently. Instead, they must invade a host organism and hijack its genetic instructions.
Explanation:
Answer:
A flu is a virus and the reason that you have to get flu shots every year is because every time a virus enters a host it is mutated by the antibodies, cells and biology of that host, so it can be passed on to another host who may not be immune to every part of this NEW virus.
Explanation:

If you poured the fluids below into a container, which would sink to the bottom?
-water with a density of 1.0 g/cm3
-vegetable oil with a density of 0.91 g/cm3
-honey with a density of 1.36 g/cm3
-air with a density of 0.00013 g/cm3
Answer:
Honey > Water > oil > air
Explanation:
Heavy density will sink and less heavy density will float
So,
Density of honey is highest so, honey will sink
than,
Density of water is higher so, vegetable oil will float
Density of oil is higher so, air will float
Honey > Water > oil > air
My category includes genetic material.

where are neutron founded?
Answer:
By 1920, physicists knew that most of the mass of the atom was located in a nucleus at its center, and that this central core contained protons. In May 1932 James Chadwick announced that the core also contained a new uncharged particle, which he called the neutron. Chadwick was born in1891 in Manchester, England.
Explanation:
Answer:
In May 1932 James Chadwick announced that the core also contained a new uncharged particle, which he called the neutron. Chadwick was born in1891 in Manchester, England.
Explanation:
Neutrons come from fusion. Let's say you push two protons together enough for them to "touch", specifically for them to experience attraction from the strong nuclear force that is stronger than electrostatic repulsion.You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there.

What are three ways energy is used by the organisms?
Answer:
Organisms use energy to survive, grow, respond to stimuli, reproduce
Explanation:
Three ways energy is used by the organism are food, nutrients, and sunlight.
What are living organisms?Living organisms are those organisms that grow, adapt, and reproduce their young ones. Organisms need energy for their biological purposes. Organisms get energy from plants and other animals. This energy is used in the form of glucose.
Cellular functions require energy, which living things must obtain from food, nutrition, or sunshine. Energy is used in a cell for the transport, synthesis, and breakdown of nutrients and molecules.
Glucose and ATP are the two types of molecules that organisms primarily use for chemical energy. In the entire biological universe, both molecules are used as fuel.
Therefore, the energy is used by the organisms in three ways that are food, nutrients, and sunlight.
