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

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.

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.
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.
That's all I have! I hope this helps with your studying. Happy learning, friend! :)
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.
A eukaryotic cell has 6 chromosomes, explain what you would get at the end meiosis.
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.
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.
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
