Answer:
The correct answer is -
A (i) a male from colony A HH and female from colony B bbhh
(ii) the offspring will be heterozygous for short brown hair
(iii) genotype 100% Hhb, phenotype - 100% short brown hair
Explanation:
It is given that parent one is from Colony A that is pure breeding for short hair which means p1 is HH and parent 2 is from colony B that is pure breeding for long brown hair that means p2 is bbhh.
Cross between HH and bbhh
Gemetes : H, H, and bh, bh,
Punnet:
bh bh
H Hhb Hhb
H HhB Hhb
Thus, the offspring will be heterozygous for short brown hair

Is there anything we as a society can do to prevent these pandemic from occurring
The only thing you can do now is to try do the necessary pre-causion, which are;
Always wear maskAlways be sanitizedAlways wear hand glovesKeep social distancingThe oxidation of a chemical occurs when
It loses electrons
It gains electrons
It shares electrons
All the above
Answer:
Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction. When oxidation occurs, the oxidation state of the chemical species increases.
Explanation:
oxidation is loss of electrons
here a trick to remember this
oil rig -> oxidation is loss. reduction is gain

Shondra takes notes in class.
Three entries in Shondra's notes are not in the right
place. What can Shondra do to correct her notes?
1. Energy
A Definition - the energy of moving objects
B. Main categories of energy
1. Kinetic - the ability to do work
2 Potential - the energy stored in objects
3. Chemical -- the energy in chemical bonds
C. Forms of energy
1. Gravitational - the energy of a rock on a hill
2 Elastic - the energy in a spring
3. Nuclear - the energy in the nuclei of atoms
4. Electromagnetic wave - the energy from the Sun
5. Electrical - the energy of flowing electrical charges
O Switch "the energy of moving objects" and "the
ability to do work" and place chemical energy under
"Forms of energy."
O Switch "the energy of flowing electrical charges" and
"the energy in a spring" and place kinetic energy
under "Forms of energy."
O Switch "the energy in the nuclei of atoms" and "the
energy stored in objects" and place nuclear energy
under "Main categories of energy."
O Switch "the energy from the Sun" and "the energy of
a rock on a hill" and place electrical energy under
"Main categories of energy."

Which statement correctly compares mass and weight?
A.Both depend on the force of gravity pulling on an object B.The basic unit of both is the kilogram C.Both mass and weight ofan object would be less on the moon than on Earth D.Weight varies with location, but mass does not vary
Answer:
D. Weight varies with location, but mass does not vary
Explanation:
Weight can be defined as the force acting on a body or an object as a result of gravity.
Mathematically, the weight of an object is given by the formula;
[tex] Weight = mg [/tex]
Where;
m is the mass of the object.g is the acceleration due to gravity.Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.
Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).
Hence, the statement that correctly compares mass and weight is that, weight varies with location, but mass does not vary. This is simply because acceleration due to gravity changes with location i.e its value varies with the planets.
what type of food is made during photosynthesis
Answer:
glucose
Explanation:
Plants, unlike animals, can make their own food. They do this using a process called photosynthesis . During photosynthesis, plants produce glucose from simple inorganic molecules - carbon dioxide and water - using light

Which event triggers the start of black hole formation?
Answer:
A stellar-mass black hole forms when a star with more than 20 solar masses exhausts the nuclear fuel in its core and collapses under its own weight. The collapse triggers a supernova explosion that blows off the star's outer layers.

Explanation:
A forest fire destroys an area. A small population of trees and a large population of birds are both affected. Which type
of limiting factor causes this?
density dependent
density independent
population dependent

Answer:
B. DENSITY INDEPENDENT
Explanation:
Density independent is a limiting factor. It affect birth and death rates of organisms through abiotic and environmental factors. A forest fire is one of the environmental factors that affects the density of a species in a given location.
