Answer:A. BW x BB
Explanation:
The parental cross that was most likely responsible for the percentages of offspring fur color, the scientist found, BW x WW. The correct option is A.
What is crossing?The exchange of genetic material between non-sister chromatids of homologous chromosomes occurs during crossing over, an enzyme-mediated process. It happens during meiotic prophase I's pachytene stage.
When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place.
Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up. The same genes may be present on the two chromosomes in different versions.
Therefore, the correct option is A. BW x WW is the result of the crossing over of offspring for a mated pair of hamsters.

Elodia is a plant that lives in water. Like all plants, elodea can make its own food via photosynthesis. Oxygen is a gas produced during photosynthesis. Photosynthesis can only happen in the presence of light. To measure the rate of photosynthesis, a piece of elodia can be placed in an inverted test tube filled with sodium bicarbonate solution. Oxygen gas produced by photosynthesis will collect at the top of the tube. The experimental set up created by a student is shown above. What is the dependent variable in this experiment?

What is the weigh of the air that is pressing down on us at sea level, in pounds per square inch ?
Answer:
Así como el agua del mar tiene un peso que actúa sobre los seres que lo habitan, también lo tiene el océano de aire que hay por encima de nosotros. Cargamos sobre nuestras espaldas casi una tonelada de aire, pero no lo notamos porque nos sostiene en pie una presión atmosférica equivalente, que se ejerce en todas direcciones.
La presión media del aire al nivel del mar es de 1.03 kilogramos por centímetro cuadrado. Esta presión disminuye rápidamente al aumentar la altura: a 3,000 metros se reduce a unos 0.7 kilogramos por centímetro cuadrado y a 8,800 metros, la altura del monte Everest, la presión es sólo de 0.316 kilogramos por centímetro cuadrado. (El aire es tan tenue en estas altitudes que los alpinistas tienen que llevar suministro de oxígeno.

true or false? Both speed and acceleration include the
direction of an object's motion.
Answer:
True
Explanation:
Hope this helps:)
To solve this, we must be knowing each and every concept related to speed, acceleration and its calculation. Therefore, the given statement is false.
What is speed?Speed may be defined as the distance traveled by an item in the amount of time it requires to travel that distance. In other words, it measures how rapidly an item travels but does not provide direction. The term "velocity" refers to the combination of direction and speed.
Acceleration is defined by the rate at which an object's velocity changes with respect to time. When an object's velocity changes, it is referred to as accelerating or to have acceleration. Speed does not include the direction of an object's motion. Acceleration include the direction of an object's motion.
Therefore, the given statement is false.

All cells and many subcellular structures are surrounded by a membrane. Assuming a typical membrane to be about 8 nm wide, how many such membranes would have to be aligned side by side before the structure could be seen with the light microscope
Answer:
25 membranes
Explanation:
A light microscope makes it possible for the scientist to view and visualize structures with a minimum of 200 nm in diameter. So, if a typical membrane is about 8 nm wide, then we can divide the minimum diameter with the given width of the typical membrane to determine the number of membranes.
SO;
[tex]= \dfrac{200 \ nm}{8 \ nm / membranes}[/tex]
= 25 membranes
So, in a light microscope, there are about 25 membranes that will align side by side to view the structure.

Note about the question:
In the GIZMO program, you will be provided with 46 chromosomes that are not paired nor in order (box superior-right). According to the chromosome image shown below, you need to look for the correct chromosomes, pair them with their homologous, and place them in their correct spot to complete the karyotype.
Answer:
Subject B sex: FemaleJustification: The last pair of chromosomes are equally large, meaning that they are two X chromosomes (XX).Explanation:
Note: You will find the complete karyotype in the attached files.
A human cell has 46 chromosomes or 23 pairs of homologous chromosomes. 22 of them are somatic chromosomes or not-sex chromosomes. The last pair, number 23, is the only sex pair.
To know if an individual is a male or a female, you just need to see the last pair of chromosomes. Pair 23 is the sex pair.
Male: The pair is formed of a short chromosome (which corresponds to Y from the male parent) and a large chromosome (which corresponds to X from the female parent)---> XYFemale: The pair is formed of two equally large chromosomes. Each of them corresponds to X, one from the male parent and the other from the female parent). ----> XXestimate the length of time that it took for CO 2 to from 200 300 ppm

Note: The question is incomplete. The complete question is found in the attachment below.
Explanation:
High temperatures or changes in pH can denature an enzyme, causing it to lose its shape and activity.
Enzymes speed up chemical reactions by lowering the activation energy which allows the reaction to proceed much more quickly.
An enzyme is considered a(n) catalyst because it speeds up a chemical reaction without being used up.
The induced fit between an active site and its substrate often strains bonds and helps the reaction proceed.
A(n) inhibitor is a molecule that can bind to an enzyme and prevent the enzyme from working.
During an enzymatic reaction, a molecule of substrate binds to the enzyme and is broken down into one or more molecules of product which are released.
The specific location within an enzyme molecule where the substrate binds is called the active site.
Lactose takes years to break down on its own. But if exposed to the protein lactase, the reaction proceeds very quickly, while lactase itself remains unchanged. Lactase is an example of a(n) enzyme.
The diploid number of chromosomes in the mustard plant, Arabidopsis thaliana, is 10. Knowing this, answer the following questions about the stages of mitosis. Part APart complete How many chromosomes will be found in each cell during prophase
Answer:
10 chromosomes
Explanation:
Ten (10) chromosomes would be found in each cell of Arabidopsis thaliana during prophase.
The prophase stage represents the first stage of the mitotic division immediately after the interphase. A diploid cell has 2n number of chromosomes and the ploidy level of a cell remains intact throughout the interphase to the prophase stage of mitosis.
At the prophase, the chromosomes of a cell only condense and become visible under the microscope. Each chromosome is seen as being consisting of two sister chromatids joined together by a structure known as the centromere.
Hence, the number of chromosomes in the cells of Arabidopsis thaliana would remain the same even at the prophase stage of mitosis.
unlike eukaryotes prokaryotes do not contain a system of internal membranes. Any organelles, proteins, and genetic material are free - floating within the cytosol. Select the description below that correctly identifies how protein synthesis differs in prokaryotic and eukaryotic cells as a result of eukaryotic compartmentalization.
A. RNA processing occurs outside of the nuclear membrane in prokaryotes and inside it in eukaryotes.
B. Translation can occur before transcription in a prokaryote but not in a eukaryote.
C. Transcription and translation can occur simultaneously in a prokaryote but not in a eukaryote.
D. Ribosomes are needed for translation of mRNA in eukaryotes, but they are not needed in prokaryotes.
Answer:
The difference in protein synthesis in prokaryotic and eukaryotic cells, due to the compartmentalization of the latter, is that transcription and translation can occur simultaneously in a prokaryote but not in a eukaryote (option C).
Explanation:
Eukaryotic cells are characterized by a true nucleus, surrounded by a nuclear membrane. Since transcription occurs in the nucleus and translation for protein synthesis occurs in the cytoplasm, the former process occurs before the latter.
In prokaryotic cells the absence of a nucleus and compartmentalization system makes it possible for transcription of DNA into RNA and translation to occur simultaneously.
The other options are not correct because:
A. RNA processing, in both prokaryotes and eukaryotes, occurs in the cytoplasm.
B. Transcription precedes translation in all organisms.
D. Ribosomes are present and are necessary for protein synthesis in both prokaryotes and eukaryotes.
