55.0 °C?
can you help. me?
Answer:1503.3 mL

Sodium metal reacts whit hydrochloric acid to produce salt and hydrogen gas. What are the reactants in this chemical reaction
Answer:
Na (sodium) and HCl (hydrochloric acid)
Explanation:
The products are the salt and hydrogen gas
Whenever you see the word react it means those are the reactants (usually whatever compound comes before and after the word). Because they are reacting with each other.
Whenever they say "is produced" those are the products
Part B Which shape of molecules do scientists think may be important for the development of life and why?
Answer:
Molecular shape (the shape that a single molecule has) is important in determining how the molecule interacts and reacts with other molecules. The Molecular shape also influences the boiling point and melting point of molecules. If all molecules were linear then life as we know it would not exist.
Answer:
Scientists think that branched molecules may be important for the development of life. That’s because amino acids have branched molecules, and they are the building blocks of proteins

A student wants to perform an experiment to test the effect of different colored lights on the growth of basil plants. She sets up an experiment where multiple basil plants are placed in six different setups; one with red light, one with green light, one with yellow light, one with blue light, one with no light and one with sunlight. In each setup the plant receives the same amount of water, soil, and size of container. What is the independent variable in this experiment
Answer:
light is the independent variable, height of the plant is the dependent variable. Dependent is the effect that based on the independent.
Explanation:
lets break it down. 1) you want to know the effect of something you apply from one thing to another. Let say, if you grow your plants under the sunlight, the plants grow taller. In this case, the sunshine is the independent variable whereas the height of the plant/how tall it can grow is the dependent variable. 2)NOW, before i give the answer. The design of the question is not good for high school students. i think your teacher thinks "light" is the independent variable. 3)However, the question contains confounding variables in it because different lights might produce different effects to the height of the plants. If you want to test if plants are exposed to light grows taller than plants do not expose to light, then you should have all the lights are the same. 4) So, all the plants should be exposed to one certain light to avoid confounding. Confounding means that either red light and sunlight are both produce the same effect whereas the other colors do not help the plants to grow taller. 5)Your teacher should test one light at a time. So, if he is testing with all different colors of light, then light is the independent variable, and height of the plant is the dependent variable.

DNA is often compared to a twisted ladder. In this analogy, what forms the
rungs of the DNA ladder?
A. Pairs of nitrogenous bases
B. Pairs of nucleotides
C. Pairs of sugars
D. Pairs of phosphate groups
The pairs of nucleotides result in the twisting of strands. Therefore, option "B" is correct.
What is nucleotide base pairing?There are five types of nucleotide bases adenine, cytosine, guanine, thymidine, and uracil. These divide into two classes of nucleotides pyrimidine and purine nucleotide bases. Pyrimidines are uracil, thymine, and cytosine whereas adenine and guanine are purine.
In RNA, adenine, cytosine, and guanine are present but thymine is replaced by uracil. Pyrimidine always binds with the purines through hydrogen bonding. Adenine binds with thymine. Cytosine binds with guanine. But when adenine pairs with uracil in RNA.
Therefore, nucleotide base pairing determines the twisting of the DNA strand depending on the type of nucleotide present.

In the Punnett square, fill in the shaded boxes with the alleles of each parent. Use B for the
dominant allele (black fur) and b for the recessive allele (white fur). THIS ONE IS A SECOND ONE PLEASE HELP
Answer:
you gotta put the small "b" for the female and all the the box will be "Bb"
The dominant allele (black fur) has alleles B and b for the recessive allele (white fur), so the offspring will all have bodies with black fur.
What is phenotype?Phenotype is the physical appearance of characters which is the result of genes which express in the cell to give a particular trait in the diagram black is dominant over white so all the offspring show a black phenotype.
Male genotype: BB
Female genotype: bb
Cross: BB X bb
Gametes: B, B, b, b
All progeny will be black having genotype Bb, Bb, Bb, Bb.
The Cross is uploaded in the image below.
Genotype is the genetic appearance of the allele which shows the gene is responsible for a particular trait.
Therefore, the dominant allele (black fur) having allele B and b for the recessive allele is crossed, and all progeny will be black having genotype Bb, Bb, Bb, Bb.

Answer the next five questions based on the following information. You are studying a particular type of spider and have identified four traits that follow simple mendelian genetics. The B gene governs body color and black body color is dominant to brown. The D gene governs whether or not the spider is poisonous, and poisonous is dominant to non-poisonous. The E gene governs eye color and black eyes are dominant to red eyes. The H gene governs hair type and hairy is dominant to hairless. Indicate your answer numerically not alphabetically. For instance, answer "2" not "two." For each answer that is not a whole number, give your answer as a fraction reduced to the lowest possible whole numbers. For instance, 3/9 would be reduced to 1/3.
How many different types of gametes can be formed by a spider that has the genotype BbDdEeHH?
If you chose a single gamete at random from a spider that has the genotype BbDdEeHh, what is the probability that the gamete would have the genotype BdEh?
You mate a BbDDEeHh spider with a BbDdEEHh spider. What is the probability that one randomly chosen offspring will have the genotype BbDdEEHH?
Answer:
a. 81/256.
b. 9/256.
b. 9 / 256.
Explanation:
The given traits in the question follow the Mendelian character. The cross between the body color where B is responsible for black color and b is responsible for brown color is as follows: Bb × Bb results in the 3/4 black color ( BB, Bb, Bb) and 1/4 brown color progeny (bb). The cross between the poisonous and nonpoisonous trait where D is responsible for poisonous trait and d is responsible for nonpoisonous is as follows: Dd × Dd results in the 3/4 poisonous trait (DD, Dd, Dd) and 1/4 nonpoisonous (dd). The cross between the eye color where E is responsible for black color and e is responsible for red color is as follows: Ee × Ee results in the 3/4 black color ( EE, Ee, Ee) and 1/4 red color progeny (ee). The cross between the hair trait where H is responsible for hairy and h is responsible for hairless is as follows: Hh × Hh results in the 3/4 hairy (HH, Hh, Hh) and 1/4 hairless (hh).
a. The cross between BbDdEeHh spider with a BbDdEeHh spider results in the 3/4black body, 3/4 black eyes, 3/4, hairy, and 3/4 poisonous progeny. Their probability is 3/4× 3/4× 3/4× 3/4 = 81/ 256.
b. The cross between BbDdEeHh spider with a BbDdEeHh spider results in the 3/4black body, 3/4 black eyes 1/4 hairless, and 1/4 nonpoisonous progeny. Their probability is 3/4× 3/4×1/4 3/4×1/4 = 9/256.
Thus, the answer is a. 81/256.

Mendel drew several key conclusions based on his observations of pea
plants. Which of the following best describes one of his conclusions?
A. A parent can pass on only one factor for each trait to its offspring.
B. An offspring that inherits different versions of the factor for a trait
will not survive.
C. Hereditary factors blend together to produce the traits of
offspring
D. Dominant hereditary factors are those that help an individual
survive and reproduce.
The best statement that describes the conclusion of the given scenario, is that parent can pass on only one factor for each trait to its offspring. The correct option is A.
What is Mendel law?Gregor Mendel proposed the law of inheritance after seven years of research on pea plants.
Mendel's inheritance laws encompass the laws of dominance, segregation, and independent assortment.
In this, the parent can pass on only one factor for each trait to its future offspring.
Thus, the correct option is A.
