a population of antelope normally graze on the abundant grasses in the savannah. however, a drought occurs and the amount of grass decreases. that year, many young, sick, and old antelope starve to death. a change in what variable lowered the antelope's population?
A change in carrying capacity lowered the antelope's population.
Carrying Capacity: An environment that can support the maximum population size of a species to sustain and grow its population is called carrying capacity. It is different for each species in a habitat because every species requires particular food, shelter, and social requirements. When a population approaches its carrying capacity, the rate of increase in a population usually slows and the birth rate equals the death rate.

Megan wants to see if mice that are fed food A or B grow at a faster rate. She measures the mass of the mice on day 1,
then divides them into two groups based on the type of food they will be given. She feeds each group the same amount of
food at the same time each day. Does Megan have a control group in this experiment?
Answer:
No, there is no control group.
Explanation:
To test various theories, experiments are usually conducted under a number of different conditions. Several considerations must be established when planning studies to ensure reproducibility, accuracy, and validity of findings.
For example, while controls are kept constant, or unmanipulated. Also, separate independent variables are strictly altered and analyzed - this guarantees validity and may show whether external influences affected the experiment. Here the variable being altered or measured is the food, and the resultant weight is the factor being observed.
In which type of solution are the cells
Answer:
A cell in an isotonic solution is in equilibrium with its surroundings, meaning the solute concentrations inside and outside are the same (iso means equal in Latin). In this state there is no concentration gradient and therefore, no large movement of water in or out.

What is Morgan hunt's experiment?
Morgan's arguments against the Mendelian and chromosomal theories were very different. Both hypothesized cellular structures or substances that somehow regulate developmental processes in an effort to explain biological occurrences. This reminded Morgan too much of the preformation theory, which held that the adult is already fully formed in the egg or sperm and dominated embryology in the late 18th and early 19th centuries.
Morgan contended in 1909 and 1910 that no single chromosome could contain particular hereditary qualities, despite the fact that he acknowledged that the chromosomes might have something to do with heredity. Additionally, he asserted that Mendelian theory was completely hypothetical because it was unable to define the actual processes of heredity, despite being able to explain and even forecast breeding outcomes.
For Morgan, the fact that each pair of chromosomes divides and that each chromosome thereafter enters a different sperm or egg cell in precisely the same way as Mendelian factors did not seem to be sufficient evidence to support the idea that the two processes are related.

DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. The option (D) is correct.
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
Moreover, DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. All these cells, the parent cell and the two new daughter cells, are genetically identical.
Therefore, DNA replication is the process of creating two identical daughter strands of DNA. DNA replication occurs in the nucleus in eukaryotic cells and in the nucleoid region in prokaryotic cells. DNA replication occurs in S phase during the cell cycle prior to cell division.

6. What is the relationship between an organism's DNA and protein specificity?
A. DNA becomes a specific part of the protein structure
B. DNA determines the ribosomal RNA sequence that becomes part of the protein structure
C. DNA determines which RNA molecules are incorporated into protein molecules.
D. DNA determines the amino acid sequence of each protein.
Answer:
The relationship between an organism's DNA and protein specificity is that DNA determines the amino acid sequence of each protein (option D).
Explanation:
Each organism's DNA molecule is formed by a specific sequence of nitrogenous bases that not only determine the amino acids that a synthesized protein will have, but also the order in which these amino acids will form the protein structure.
The steps in which this occurs can be summarized as follows:
The sequence of nitrogenous bases of a DNA strand is transcribed into the mRNA, which will go into the cytoplasm. The sequence of bases in the mRNA is organized into triplets of bases, called codons, each of which encodes a specific amino acid. During translation, each codon will indicate the amino acid that will be coupled to a protein molecule in a specific order.According to this, the DNA determines the amino acids sequence that will be in a specific protein molecule.

a common sign of pneumothorax is a shift of the trachea towards the affected lung as air pressure sucks the lung away from the midline
The statement is false that in pneumothorax there is a shift of the trachea towards the affected lung as air pressure sucks the lung away from the midline.
Pneumothorax is the condition where the lung collapses. All the air present inside the lungs is pushed out. There occurs a tracheal shift to the opposite side during the lung collapse, but the lung is not moved away from the midline.
Lungs are the main respiratory organ of the body. They are involved in the exchange of air from the blood. The lungs comprise of several very small air sacs called alveoli. These alveoli increase the surface area of the lung and hence increase the ventilation.

Explain the energy transformation that occurs when a person exercises.
Answer:
Electrical energy is defined as the energy flowing through a device due to the flow of electrons or charges from one point to another.
The energy present within an object or material due to the sum of its motion and potential energy is known as mechanical energy.
Thermal energy is defined as the energy present within an object because of the motion of its particles.
So, when we plug in and turn on a hair dryer then electrical energy starts to flow. As a result, some of its molecules will gain kinetic energy and some will have potential energy.
Hence, its sum will lead to formation of a mechanical energy. Since, this mechanical energy gets converted into thermal energy due to which hairs get dry.
Thus, we can conclude that the energy transformation that occurs when a hair dryer is plugged in and turned on is that electrical energy transforms into mechanical and thermal energy.

Explanation:
looked it up on the internet
The difference in long-distance signaling in plant and animal cells is plants do not have a nervous system, whereas mammals have developed them to carry information signals from one region of the body to another.
What is long-distance signaling?Long-distance endocrine signaling involves the production of signals by specialized cells and the release of those signals into the bloodstream, where they are transported to target cells in far-flung regions of the body. Hormones are signals that are created in one area of the body and move through the bloodstream to distant locations.
Therefore, plants lack a nervous system, whereas mammals have one built to transmit information signals from one part of the body to another, which makes long-distance signaling different between plant and animal cells.
