Answer:
If a eukaryotic cell has 6 chromosomes, the end result after meiosis is two daughter cells with 3 chromosomes each.
Explanation:
Meiosis is the process of cell division by which sex cells or gametes are formed. It is a mechanism of reductive division, since the chromosomal charge of a eukaryotic cell —diploid— is reduced by half, that is, haploid cells are obtained.
A diploid eukaryotic cell with 3 pairs (6) of chromosomes, after meiosis produces two haploid daughter cells, with 3 chromosomes each.
This process of reductional division, where the gametes are obtained, aims to ensure that when the gametes of each parent join together they form a diploid cell, the zygote.
An igneous rock is found on the ground and has no identifiable crystals. What is the most likely origin of this rock? molten material that cooled slowly
molten material that cooled quickly
rock that was eroded by surrounding rocks
rock that was exposed to extreme pressure
Answer:
Answer is D because extreme pressure could cause something to happen to other things that might change or take place
Explanation:
Answer: the awnser is D
What does the fact that all organisms use essentially the same genetic code suggest about the origin of life?
Answer:
Well this proves that all living things may be related.
Explanation:
For example, when our ancestors had kids, their kids had their DNA, when those kids had kids, they had some DNA from their grandparents and their parents. DNA is shared by reproduction.

Is granite a igneous rock?
Answer:
Granite, coarse- or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth's crust, forming by the cooling of magma (silicate melt) at depth.
Explanation:
Which of these parts of the membrane help large molecules pass through it?
A. Phospholipid bilayers
B. Phosphorus groups
C. Globular proteins
D. Fatty acids
Answer:
A. Phospholipid bilayer
Explanation:
Cell membrane is a selective permeable structure in all living cells that allows the passage of some molecules and disallows some. This function of the cell membrane is attributed to the PHOSPHOLIPID BILAYER CONTENT of its structure.
The phospholipid bilayer contains both a hydrophobic end (water fearing) and hydrophilic end (water loving). The interaction of the molecules with these regions of the membrane serves as the basis for the movement of molecules across the cell membrane.
Answer:
Globular proteins! The other answer is sadly wrong.
Explanation:
I just took the quiz. Many globular proteins positioned throughout the cell membrane help the large, polar molecules across. These globular proteins in the cell membrane are the membrane proteins.
Also, I accidently put a 1 star on my own answer, but it's correct.

Identify the structures of skeletal muscle.
muscle fiber
muscle
fascicle
myofilament
myofibril
Answer:
1. Muscle: soft, contractile tissue important to produce force and motion in animals.
2. Fascicle: multiple bundles of skeletal muscle fibres which is surrounded by a type of connective tissue called perimysium.
3. Muscle fibres: bundles of cylindrical organelles myofibrils formed by the fusion of myoblasts via myogenesis process.
4. Myo-fibril: basic unit of a muscle cell made of thick and thin myofilament arranged in parallel columns along the length of muscle fibres.
5. Myo-filament: strands of actin and myosin proteins which pack a muscle fiber and are force generating structures.

The image below shows salamander skin cells as viewed under a microscope. The activity occurring inside the rectangle best supports which scientific theory?
Temand win PDB 1000
Appeared in The
O cell theory
O germ theory
O gene theory
O endosymbiotic theory
Type here to search
Answer:
A. Cell theory.
Explanation:
The image above shows salamander skin cells as viewed under a microscope. The activity occurring inside the rectangle best supports a scientific theory known as cell theory with respect to cell division.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cell theory states that cell is the basic unit of life, all living organisms are made up of one or more cells and they typically arise from existing cells i.e pre-existing cells give rise to new ones through the process of cell division.
From the image of the salamander's skin cell, we can see that it comprises of many cells and are these look very much alike, meaning they are from pre-existing cells.
Is it possible for an inverted pyramid to exist
Answer:
An inverted pyramid of numbers can be found in an ecosystem where the community contains a few producers with a very large biomass that support a larger number of smaller consumers. An inverted pyramid of numbers can also be found in an ecosystem where the community contains parasites.
the phenomenal having lowest acidity is
Answer: Alcohols are considered neutral with pKa values similar to water. In aqueous solutions, phenols are weakly acidic and lower the pH of a solution
Explanation:
which of the following statements describes a proton of an atom?
a. has a negative charge and is located in the nucleus
b. has a positive charge and is located in outer energy levels
c. has no charge and is located in the nucleus
d. has a positive charge and is located in the nucleus
Answer:
d. Has a positive charge and is located in the nucleus
Memory technique:
Think of the "p" and proton and the "p" in positive.
Think of the "neu" in neutron and "neu" in neutral.
Think about electrons and electricity. Touching something "elec"tric would hurt, or give you negative feelings.
Electrons revolve around the cell while protons and neutrons are a part of the nucleus because negative and positive things would not get along.

Can someone help? I don’t understand this at all.
Answer:
1. Ff and Ff and I thinks it's 75%
I think genotypic ratio is 3:4
2. Pp and pp and I think it's 50%
I think genotypic is 2:4
Explanation:
Haven't done this since 7th so I hope it helps
I don't understand the phenotypic ratio though sorry
