When a novel property emerges that was not present at the simpler level of organization. a. New property b. Evolution c. Emergent property d. Advancing property e. Natural selection
C. emergent property is the answer.
Emergent properties are properties that a collection or complex system has, but its individual members do not. Failure to recognize that property is urgent or incidental can lead to the fallacy of division.
In other words, emergent properties are properties of a group of objects that are not found in individual objects, such as insects, atoms, and buildings. Examples of emergent properties are cities, brains, ant colonies, and complex chemical systems.
Some examples of emergent properties are those of life where life begins to emerge at the cellular level. What is under the cell is not alive. The cells then interact and come together to produce other emergent properties such as tissues, organs, organisms, and populations.

Primary varicoceles are associated with all of the following, except retroperitoneal mass.
Veins in your scrotum that expand cause a varicocele (the pouch of skin that holds your testicles Palpable intratesticular mass). The pampiniform plexus is the name given to these veins. Ten to fifteen males out of one hundred have varicocele and causes infertility. It is comparable to developing varicose veins in your leg.Varicoceles occur when the scrotal pampiniform plexus veins expand. Similar to varicose veins are these veins (twisted, swollen veins, found in the leg.) Varicoceles develop during adolescence. Over time, you might start to notice them more and they might get bigger.

Can u think of three factors which might affect how much energy someone will need
Gender, age and body weight are the three factors.
What are the effects of gender, age and body weight on energy expenditure?Body weight:
Energy consumption while at rest is determined by body size and weight. Due to the higher maintenance costs associated with a larger body, a heavier person has a higher resting energy requirement. The most unpredictable part of overall energy expenditure is activity-induced energy expenditure. Since larger subjects' activity energy expenditure is not higher in proportion to the expense of moving with a higher body weight, smaller and leaner subjects often move more. As a result of changes in body size and body composition, eating causes variations in energy expenditure.
Gender:
In comparison to girls of the same size and age, adult males frequently have 10–20 percent more muscle mass. Because muscle burns more calories than fat, men have greater basal metabolic rates (BMR). As a result, men need 5–10% more energy than women.
Age:
Compared to adults, children and adolescents require more energy for growth and development. As people age, their body composition changes and their energy needs decrease, resulting in a decrease in BMR. As people age, many of them become less active.

____________ is translated by the ribosomes and contains the code that specifies the sequence of amino acids in a polypeptide chain.
mRNA (Messenger RNA) is translated by ribosomes and contains the code that specifies the sequence of amino acids in polypeptide chain.
A single-stranded ribonucleic acid molecule is known as messenger RNA(mRNA) plays a major role in translation.
Translation is the method by which an mRNA codes for a certain protein. mRNA provides the template for protein synthesis.
The ribosome translates the mRNA that is produced from the DNA into a chain of certain amino acids and protein synthesis is facilitated by this amino acid sequence.
The genetic code, which connects the DNA sequence to the amino acid sequence of proteins, is used to "read" the mRNA. Each group of three nucleotides in mRNA forms a codon, and each codon corresponds to a particular amino acid (triplet code).
Thus mRNA contains the code that specifies the sequence of amino acids in a polypeptide chain.

While doing field research, two scientists discover a new species of plant. They take the plant back to their lab to watch how it grows and reproduces. Soon, the plant begins to produce a small purple flower. Upon further investigation, the scientists discover that the plant's seeds contain two embryonic leaves.
Which group could the plant belong to? Check all that apply.
As the new species of plant produced purple flowers, so, the plant belongs to the angiosperms group. Also, the seeds of the plant contain two embryonic leaves, so, the plant must be a dicot.
Out of all five divisions of plants, only the plants that come under the Division Angiosperm can bear or form flowers. That's why angiosperms are also called flowering plants. Angiosperms are further divided into two groups based on the number of embryos that are produced from seeds on germination. If the germinating seeds contain only one embryo leaf, then we call them monocots while the seeds that contain two embryo leaves during their developing seeds, then they are called dicots.Thus, the plant that is discovered by scientists comes under the angiosperm group and further into the dicot group. Dicots have two embryo leaves on germination of their seeds and they also form flowers.

If the population is in Hardy-Weinberg equilibrium, the genotype frequencies should be 0.49 AA, 0.42 Aa, and . 09 aa.
Frequency of genotypes "AA" and "Aa". The frequency of AA is equal to p2 and the frequency of Aa is equal to 2pq. Therefore, using the above information, the frequency of AA is 16% (that is, p2 is 0.4 x 0.4 = 0.16) and Aa is 48% (2pq = 2 x 0.4 x 0.6 = 0.48).

The lack of adaptations to the habitat most likely caused the walleye to move to a different river.
Adaptation
It is a biological mechanism that increases the chance of its survival in a new environment or the changes in the existing environment. Adaptation occurs as a result of evolution and allows the organism to survive and reproduce efficiently in its environment.
Physical adaptations include accumulating changes in the physical characteristics of an organism that help them to survive and reproduce better. Example: evolution of long necks in giraffes.
Behavioral adaptations are changes in the behavior or habits of organisms that help them to sustain in a changing or new environment. Example: Hibernation.
Due to some reason, the walleye were not able to adapt to the environment of the east river which is why they must have moved to a new river despite the presence of a lot of prey.

What is one of the main characteristics of secondary granules in the neutrophilic granulocyte cytoplasm
One of the main characteristics of secondary granules in the neutrophilic granulocyte cytoplasm is that secondary granules will become pink/tan and will cause the basophilic color to lighten.
Promyelocytes, metamyelocytes, and myelocytes are the precursors of neutrophils, which make up the majority of the white blood cell population. The immature neutrophils are usually found only in the bone marrow.
Myeloid maturation sequence is the next stage of myelocyte. The cytoplasm of this cell starts to produce specific, secondary granules. If the cell is destined to be a neutrophil these secondary granules will be pink/tan and will further cause the basophilic color to lighten and break up. At the beginning of neutrophilia, these secondary granules are most obvious in the golgi area.
As the cell matures closer to a metamyelocyte, they fill the entire cytoplasm. While the cytoplasm shifts to producing secondary granules it also loses the prominence of its primary granules.
