Answer:
25% of the progeny with genotype S3S4 is expected to express 5 units of color
Explanation:
Available data:
Skin color in a certain species of fish is inherited via a gene with four different allelesallele S1 confers one unit of color, S2 has two units, S3 has three units, and S4 confers four units.Cross:
Parentals) S1 S3 x S2S4
Gametes) S1 S3 S2 S4
Punnett square) S1 S3
S2 S1S2 S2S3
S4 S1S4 S3S4
F1) 1/4 = 25% of the progeny is expected to be S1S2, expressing 3 units of color ⇒ allele S1 provides one unit, allele S2 provides two units of color
1/4 = 25% of the progeny is expected to be S2S3, expressing 5 units of color ⇒ allele S2 provides two units, allele S3 provides three units of color
1/4 = 25% of the progeny is expected to be S1S4, expressing 5 units of color ⇒ allele S1 provides one unit, allele S4 provides four units of color
1/4 = 25% of the progeny is expected to be S3S4, expressing 7 units of color ⇒ allele S3 provides three units, allele S4 provides four units of color
25% of the progeny with genotype S3S4 is expected to express 5 units of color
the genetic code is read in groups of three nucleotide bases known as
Genetic codes are sets of three nucleotides that specify an amino acid. The three-nucleotide base read in the group is known as a codon.
What is a codon?A codon is a set of three nucleotides that codes for the genetic code of the deoxyribonucleic or the ribonucleic acid. The information in it is translated into proteins.
A codon also codes for the stop and start signal of the translation sequence. Each codon codes for particular amino acids and results in the formation of the proteins for cellular function and activity.
Therefore, the genetic code in a set of three is called a codon.

What is a lymph node?No lymph nodes exist in the central nervous system. The lymph nodes are more likely to gather in three locations on each side of the body.
The inguinal nodes in the groin, axillary nodes in the armpit, and cervical nodes in the neck are where these sites are found.
The typical lymph node is enclosed by a connective tissue capsule, which divides it into lymph nodules. The lymph nodules, which are dense aggregations of lymphocytes and macrophages, are divided by lymph sinuses.
Therefore, there are several locations throughout the node's perimeter where afferent lymphatics, which carry lymph there from the periphery and enter the node on its convex side, may be found.

Answer:
Hello that's the answer and thank you
Explanation:
make me brainliest pls
Xylem and phloem are the types of tissues found in the vascular bundle of plants.
What is the vascular bundle of plants?
In animals, the bloodstream is used to transport nutrients throughout the body. This function is carried delivered via the vascular system, a network of tissues and fibers in plants.
The xylem and the phloem are the two primary tissue types that make up the vascular system. Water and dissolved minerals are distributed upward through the plant through the xylem, first from roots to the leaves. Food is transported from the leaves to the roots through the phloem.
A mature woody stem or root's principal component is made up of xylem cells. They are arranged vertically in the heart of the plant, creating a column that transports water and minerals taken up by the roots up the stem and onto the leaves.
Transporting the food that the leaves have produced downward via the stem is a similar network of phloem cells that line the outside of the xylem.
Therefore, the xylem and phloem are present in the vascular system of plants.

Using the explicit formula, calculate how far the students will be swimming on week 10 using Ernest's schedule.
Ernest would be swimming at 3.25 units on week 10
The explicit formula is given as:
[tex]a_n = a_1 + (n - 1) \times d[/tex]
Also, we have the following parameters
[tex]a_1 =1.0[/tex] -- the initial distance
[tex]d =0.25[/tex] --- the difference between concurrent distances
In week 10, the value of n is 10.
Next, substitute 10 for n in the explicit formula [tex]a_n = a_1 + (n - 1) \times d[/tex]
So, we have:
[tex]a_{10} = 1.0 + (10 - 1) \times 0.25[/tex]
Subtract 1 from 10
[tex]a_{10} = 1.0 + 9 \times 0.25[/tex]
Multiply 9 by 0.25
[tex]a_{10} = 1.0 + 2.25[/tex]
Add 1.0 and 2.25
[tex]a_{10} = 3.25[/tex]
Hence, Ernest would be swimming at 3.25 units on week 10

A. gamma rays
B. infrared radiation
C. microwaves
D. x-rays
Given what we know, we can confirm that both gamma rays and x-rays can be used to slow the decay process in foods.
What are gamma rays and x-rays?Both of these are forms of ionizing radiation. Applying these to food is known as food irradiation. What this accomplishes, is that the food that is irradiated will have its chemical bonds altered, slowing the decay process.Therefore, since both gamma rays and x-rays offer ionizing radiation to the food, which affects the chemical bonds and allows the food to have a longer shelf life, we can confirm that they can be used to slow the decay process in foods.

Which of these is FALSE?
a
Cells use ATP for cell work
b
Breaking down glucose gives off energy
c
Breaking down ATP gives off energy
d
1 ATP has more energy than 1 glucose
Answer:
D is false
Explanation:
D is false because after breaking down 1 glucose, around 36-38 ATP will be produced from ADP
A is true because cells use ATP for work
B is true, as breaking glucose makes ATP, which is just stored energy
C is true too, since ATP is an ADP connected to a phosphate. This bond contains energy and detaching the phosphate will power parts of the cell, for instance active transport systems.
1. Describe the flow of energy from the sun to a producer, like grass, and then to a consumer, like a rabbit. 100 points!!! Not a scam!
Answer: The sun produces energy to the solar panel the sollaer panel produces energy to my house
Explanation:
The Sun then provides energy to the grass via the photosynthesis process. The rabbit consumes the grass and absorbs its energy.
What is flow of energy?The flow of energy through living things within an ecosystem is referred to as energy flow.
All living organisms can be classified as producers and consumers, and those producers and consumers can be classified further as a food chain. Each level of the food chain is referred to as a trophic level.
The Sun then provides energy to the grass through photosynthesis. The rabbit consumes and absorbs the grass's energy.
Finally, the snake consumes the rabbit and absorbs its energy. Energy travels from the Sun and is consumed by each consumer along the chain.
Thus, this way, energy flows in an ecosystem.
