How do I make a Punnet Square without knowing if traits are Dominant or Recessive? I cannot refer to the parents of the current generation, so I have to rely on that generation to create a theoretical next generation.
If you are referring to a previous generation, that would probably mean that the traits they have are the dominant ones
Explanation:
if you know all the traits possible, then the ones the parents have of a previous generation are most likely the dominant ones, from there, you can hopefully figure out another generation. could you attach a picture if this didn't help? thanks

Question 6 options:
a. Once the ovum leaves the ruptured follicle it is captured by the uterus and then directed into the Fallopian tube, where it is pushed along towards the oviducts.
b. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
c. Once the ovum leaves the ruptured follicle it is fully matured and propels itself into the Fallopian tube, where it moves along towards the uterus.
d. Once the ovum leaves the ruptured follicle it is captured by the cervix and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
The correct answer is B. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
Explanation
Ovulation is a process that occurs during the menstrual cycle that occurs around day 14 of the cycle. In the ovulation process, the eggs go through different places before reaching the uterus (their final destination). The first step is when the egg leaves the broken follicles. The second step is when it is taken to the fallopian tubes (place where fertilization occurs) through the fimbriae. The third step is when the egg uses the cilia to reach the uterus.

Absolute strength measures maximum force. Dynamic strength measures repeated motions. Elastic strength measures exertion of force rapidly. and Strength endurance measures fatigue resistance.
What is Muscle strength ?Physical strength and muscular endurance share some characteristics, they also differ significantly. Your ability to apply force or lift weights is a measure of your muscular strength. Using heavier weights for fewer repetitions helps develop muscular strength.
The term "muscular endurance" describes a muscle's capacity to endure prolonged periods of repeated contractions against opposition.
Long-distance running, cycling, or swimming, as well as bodyweight exercises and circuit training, are exercises that increase muscle endurance.

Describe hydrophobic interactions, the conditions under which they occur, and the probable influence they have on protein structure. Group of answer choices These are nonpolar side chains of amino acids that tend to associate to form hydrophobic clusters usually away from the protein surface. These are nonpolar side chains of amino acids that tend to destroy hydrophobic clusters away from the protein surface. These are polar side chains of amino acids that tend to associate to form hydrophobic clusters usually close to the protein surface. These are polar side chains of amino acids that tend to destroy hydrophobic clusters close to the protein surface.
Answer:
Nonpolar side chains of amino acids tend to associate to form hydrophobic clusters usually away from the protein surface.
Explanation:
Hydrophobic interactions are defined as the relationship between the low water soluble molecules named hydrophobes and water. They contains a long chain of carbon atoms and are usually considered as a nonpolar molecules.
They occur when the non polar amino acids are associated to produce the hydrophobic clusters that are usually away from the surface of the protein.
How is an RNA molecule different from a DNA molecule?
RNA is single stranded and composed of nitrogenous bases, a phosphate group, and a pentose sugar.
RNA is single stranded and composed of nitrogenous bases, a phosphate group, and a tetrose sugar.
RNA is a double-stranded helix and composed of nitrogenous bases, a fatty acid, and a pentose sugar.
RNA is single stranded and composed of nitrogenous bases, an amino acid, and a hexose sugar.
Answer:
RNA is single-stranded and composed of nitrogenous bases, a phosphate group, and pentose sugar.
Explanation:
RNA is different from DNA because instead of having two matching bases; it is only made of one strand of nitrogenous bases. These bases are attached to the phosphate, which holds the whole strand of RNA together. The sugar acts as a carrier for the bases. The sugar in RNA is known as ribose and contains 5 carbon molecules. This is why it is called pentose sugar.

In an animal, which part of the cell is responsible for keeping viruses out?
Answer:
here's your answer
Explanation:
Once attached to a host cell, animal viruses may enter in a variety of ways: by endocytosis, where the membrane folds in; by making channels in the host membrane (through which DNA or RNA can be injected); or, for enveloped viruses, by fusing with the membrane and releasing the capsid inside of the cell.In an animal cell, the lysosome is an organelle of the cell that is responsible for destroying the virus. The virus can enter the cell via endocytosis, but the lysosome can degrade and destroy it to protect the cell.
What is the function of the immune cell?Immune cells such as neutrophils, macrophages, and others play a role in protecting the body from foreign harmful pathogens. They have specific structures for doing so.
Because not all body cells have MHC II or toll-like receptors, cells have different organelles to protect themselves. Cells have lysosomes within them. Lysosomes have an acidic environment that can degrade viral proteins.
When the virus is phagocytosed by the cell, it combines with the lysosome. The lysosome degrades the virus with the help of hydrolyzing enzymes and throws it out of the cells. These are collected by other cells.
Hence, the lysosome of the cell degrades the virus and keeps it out.

If the gene sequence of DNA is A T T C G A C T C G what will the complementary mRNA sequence be that is made during transcription?
Answer:
U A A G C U G A G C
Explanation:
The complementary bases in RNA are the same as DNA with G-C (guanine to cytosine).
But, they are different in that RNA has A-U (adenine to uracil) instead of A-T (adenine to thymine).
Using these RNA base pairs of G-C and A-U, create the complementary mRNA sequence:
A T T C G A C T C G
Translate:
U A A G C U G A G C
So, the complementary mRNA sequence will be U A A G C U G A G C

True or False: As ATP is used in the myofilaments, mitochondrion, and cytoplasm of muscle cells, heat is released. The circulatory system takes heat to the skin’s surface to dissipate to the environment. People sweat to help cool down.
Answer:
- As ATP is used in the myofilaments, mitochondrion, and cytoplasm of muscle cells, heat is released. True
- The circulatory system takes heat to the skin’s surface to dissipate to the environment. True
- People sweat to help cool down. True
Explanation:
Muscle contraction occurs when myosin heads bind to actin to pull it inwards. The energy for muscle contraction is provided by the hydrolysis of ATP molecules. ATP hydrolysis also provides energy for cellular processes in the mitochondria and cytoplasm of muscle cells. During ATP hydrolysis, heat is released, thereby the increase in ATP hydrolysis increases heat production (approx. 60% of the energy released from ATP hydrolysis produces metabolic heat). Moreover, on hot days, the cardiovascular system composed of the heart and blood vessels dissipates heat through the blood flowing in veins and arteries, which moves closer to the skin surface (and therefore heat is lost). Finally, sweating refers to the process of exocrine secretion of the sweat glands that release salty water through the pores of the skin. As sweat evaporates, it helps to cool down the body and regulate its temperature.

A study is done on a group of families in Sweden that are segregating a genetic disorder. A statistical estimate of whether two genes, or a gene and a disease gene, are likely to be located near each other on a chromosome (called Lod-score analysis) indicates that the gene involved in the disorder shows a strong likelihood of linkage with a particular DNA marker locus. However, a second study done in Italy with other families segregating the same genetic disorder results in lod-score values that strongly indicate the lack of linkage between the gene and the same DNA marker locus. Assuming that both studies were performed appropriately, what is the most likely explanation for the different outcomes
Answer:
This disorder is caused by mutations in either of two different genes; one of these genes is linked to the DNA marker locus and the other gene is not.
Explanation:
A gene marker (also known as a molecular marker) is defined as a particular DNA sequence that has a specific physical location on a given chromosome. The gene markers are always physically linked with genes of interest, thereby they are useful for identifying patients affected by a given disease and/or a particular phenotypic trait. In this case, in the first study, genetic variation of the marker has been shown to be useful to map one locus that is associated with the disease phenotype. However, in the second study, a second locus that is not linked to the marker can segregate independently, thereby showing different results from the first study (in this case, it is imperative to develop a new genetic linkage analysis to discover genetic markers linked to the second gene, which is also responsible for the disease phenotype).
