If in a monohybrid cross you end up with a 1-2-1 genotype ratio for the offspring, What can you deduce about the parents?
Answer:
both parents are heterogeneous
Explanation:
This can be determined by a punnet square. If a punnet square is created with two heterogeneous parents (example: Bb x Bb), it will result in a 1:2:1 ratio for the genotypes. 1 with two dominant alleles (BB), 2 with one dominant and one recessive allele (Bb), and 1 with two recessive alleles (bb). 1 BB-2 Bb-1 bb
Protein kinases are enzymes that act on other enzymes by adding phosphates groups. When the enzyme is phosphorylated, it changes its activity (it becomes more or less active, depending on the enzyme). This regulatory mechanism of enzymatic activity is called
Answer:
The regulatory mechanism of enzymatic activity is known as Phosphorylation
Explanation:
Phosphorylation usually results in a functional change of the target protein (substrate) by changing enzyme activity, cellular location, or association with other proteins.
Answer:
The feedback inhibition regulatory mechanism. They do this by causing phosphorylation of the other enzyme.
Explanation:
There are two ways by which enzymes can be controlled or regulated. This includes
1. Controlling the synthesis of the enzyme (this relates to a genetic control)
2. Controlling the activity of the enzyme (feedback inhibition).
In this example here, the protein kinases act on other enzymes by adding phosphates groups bringing about phosphorylation and controlling or regulating the activity of these enzymes. Thus, this type of regularly is the feedback inhibition regulatory mechanism.

Sheryl is observing ovarian slides taken from a female ape. All the cells show crossover chromosomes. What is this stage?
ОА
meiotic prophasel
ОВ.
meiotic prophase II
Ос.
meiotic metaphase
Answer:
meiotic prophasel
Explanation:
Crossing-over is a unique phenomenon that only occurs during meiotic division or gamete formation. It is the process whereby non-sister chromatids of homologous chromosomes exchange a portion of the their chromosome.
Crossing-over occurs specifically in the Prophase 1 stage of meiosis, where homologous chromosomes lie side by side to form a TETRAD structure and exchange their chromosomal segment. Crossing-over aims at promoting genetic diversity among sexually-reproducing organisms.
Therefore, an ovarian slide observed to show crossing-over occurs at the Prophase I stage of meiosis 1.

A. Origin of Life- Scientists Hypotheses Disproving Spontaneous Generation (Word Bank: air, sealed, open, bacteria, gauze, spontaneously) Through the early 1800s, people believed organisms could ________________ develop, an idea known as spontaneous generation. In 1668, many believed maggots were spontaneous generated from rotting meat. Francis Redi’s experiment disproved this by experimenting with meat in open_jars, tightly snealed_jars and jars covered with cloth netting. It was also believed that bacteria spontaneously generated in broth. Lazzaro Spallanzani removed the _________ from a flask, __________ the broth and sealed the flask. No bacteria generated without exposure to the air. Some people still supported spontaneous generation but thought that air was a ________ force, necessary for it to occur. In 1859, Louis Pasteur completely disproved spontaneous generation by using a special flask that allow ______________ in but captured bacteria before it could get to the broth. No _________________ grew in the flask after boiling = no spontaneous generation. 2. First Life (Word Bank: eukaryotes, prokaryotic, variety, self-replicating, organic, photosynthesis, oxygen) Earth’s atmosphere had to be very hot and with little oxygen for the first ________________ molecules to first form.

How are the daughter cells produced by meiosis
different from those produced by mitosis?
Answer:
In mitosis, the daughter cells have the same number of chromosomes as the parent cell. But, in while meiosis, the daughter cells have half the number of chromosomes as the parent.
The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred.
Explanation:
In mitosis, the cells of the daughter are as many chromosomes as the cell of the parent, and the cells of the daughter in meiosis are as many as the chromosome of the parent. Mitosis-generated daughter cells are similar, while meiosis-generated daughter cells are special as they cross.

Which of the following statements is true? Somatic cells are diploid, meaning that they have two copies of the human genome. Somatic cells are haploid, meaning that they have one copy of the human genome. Sperm and egg cells are diploid, meaning that they have two copies of the human genome. Stem cells are haploid, meaning that they have one copy of the human genome.
Answer:
Somatic cells are diploid, meaning that they have two copies of the human genome.
Explanation:
Somatic cells are any of the cells found in the body which are not gametes or germ cells. They are diploid in that they contain two sets of chromosomes, one inherited from each parent.
A germ cell is a cell containing half the number of chromosomes (are haploid) and able to fuse with one from the opposite sex to form a new individual. They undergo the process of mieosis to become haploid cells.
Stem cells are undifferentiated or unspecialized cells with self-renewal capacity. They can divide through mitosis limitlessly to replenish other cell types of multicellular organisms throughout their life. They contain two sets of chromosomes (are diploid) one from each parent. They of two types: embryonic and adult somatic stem cells.
True: Somatic cells are diploid, meaning that they have two copies of the human genome.
False: Somatic cells are haploid, meaning that they have one copy of the human genome.
False: Sperm and egg cells are diploid, meaning that they have two copies of the human genome.
False: Stem cells are haploid, meaning that they have one copy of the human genome.
In anaphase I of meiosis, ______ separate while in anaphase of mitosis ______ separate microtubules, microfilaments spindle fiber, nuclear envelope nuclear envelope, spindle fiber sister chromatids, homologous chromosomes homologous chromosomes, sister chromatids
Answer:
In anaphase I of meiosis, the homologous chromosomes separate while in anaphase of mitosis the sister chromatids separate
Explanation:
During meiosis I, the chromosomes are duplicated (i.e., they are bivalents). Moreover, in Anaphase I, the sister chromatids continue attached to each other, while homologous bivalent chromosomes already condensed in prophase I separate.
The spindle fibers are a type of microtubule that helps to separate the genetic material during cell division.
The microfilaments are structures formed by actin subunits and they form a contractile ring during cytokinesis, or cytoplasm division.

What forms of subtle implicit discrimination do you recognize around you? Explain
Answer:
Examples include:
1. A female employee not given certain rigorous projects which she is interested in. This leaves her wondering if her gender could be the cause of the exemption.
2. A Chinese employee who was exempted from a get together at his workplace (which is dominated with Africans) and he wonders if it was a result of his nationality.
Explanation:
Discrimination is the act of segregating or exhibiting prejudice on a particular set of people for reasons such as race, gender, age, or sex. Discrimination could be overt or subtle. Overt discrimination is frontal and more recognizable when compared to subtle discrimination which is more blurry and difficult to recognize.
For example, if a prospective employer expressly says that female employees are not needed for a role, it is quite easy to recognize this as a form of discrimination. This illustrates overt discrimination. But then subtle implicit discrimination are more difficult to recognize. They leave the victim wondering if the act was actually discriminatory and it is quite harder to lodge legal complaints about these types of discrimination. Examples are some of these stated above.
The pedigree on the right shows the inheritance pattern for an X-linked recessive disorder. The mother of the individuals circled in pink is not shown on the pedigree. Based on the phenotypes of these individuals and their father, what are the possible genotypes of their mother? Check all of the boxes that apply
Answer:
The right answers are: XAXA and XAXa
Explanation:
A genetic disease is caused by an X-linked recessive inheritance when:
1. the gene present on the x linked chromosome, involved in the mutation.
2. The presence of both mutant alleles is necessary for the disease to be expressed in a female.
As per the image, the mother has always transferred a healthy allele (XA) so the answers are the genotypes carrying this allele.
Thus, the right answers are: XAXA and XAXa
