Answer:
They are able to take up and store more oxygen in their muscles
Explanation:
According to Oxford dictionary, myoglobin is ''a red protein containing haem, which carries and stores oxygen in muscle cells. It is structurally similar to a subunit of haemoglobin.''
The fact that Tibetans have a high level of myoglobin implies that they are able to take up and store more oxygen in their muscles since myoglobin is involved in storage of oxygen in muscle cells. Hence elevated levels of myoglobins enables the muscle cells to work more effectively.

The solutions in the two arms of a U-tube are separated by a membrane that is permeable to water and glucose but not to sucrose. Side A is filled with a solution of 4M sucrose and 2M glucose. Side B is filled with 2M sucrose and 3M glucose. Initially, the solution in side A, with respect to side B is______________.
Answer:
hypertonic
Explanation:
The solution in side A is hypertonic with respect to side B.
A hypertonic solution is a solution with a higher concentration of solutes in comparison with a neighbouring solution separated by a selectively permeable membrane.
In terms of both sucrose and glucose concentrations, the solution in side A is higher than the solution in side B of the U-tube. Hence, side A is hypertonic to side B.
A hypertonic solution is as opposed to a hypotonic solution with the latter having a lower concentration of solutes as compared to a neighbouring solution. Isotonic solutions have equal solute concentrations with their neighbouring solutions.
In the Punnett square fill in the shaded boxes with the alleles of each parent use B for the dominant allele (black fur) and b for the recessive allele (white fur)
Answer:
Explanation:
Under the male put BB
Next to the female bb
then first row should be Bb Bb
second row should Bb Bb
Here, all the alleles of the black parent are dominant and are represented as BB, and those of the white parent are represented as bb, and they both are purebred dominant and recessive alleles that have produced all dominant black (Bb) offspring.
What is Punnett Square?A Punnett square is a diagram used to predict the possible outcomes of a genetic cross between two parents. In this case, the parents have different alleles for a gene that determines the color of their fur. The dominant allele B produces black fur, while the recessive allele b produces white fur. The Punnett square is arranged in a grid, with each box representing one possible genotype for the offspring. The top row and left-hand column of the grid represent the alleles that each parent can contribute to their offspring. In this case, both parents are purebred,as expressed below.
Hence, black parents are dominant and are represented as BB, and those of the white parent are represented as bb, and have produced all dominant black offspring.

The discovery of a buried crater (about 200 km across) near Chicxulub, Mexico.
What is extinction?
Extinction is defined as the disappearance of an organism or a group of organisms as a result of environmental factors or changes in the members' evolutionary processes.
It can also be defined as an evolutionary process that causes a species or population to go extinct.
When there are no longer any living members of a certain animal or plant species anywhere in the globe, the species has become extinct.
Generally speaking, species disappear for the following reasons:
Genetic and demographic phenomena.Habitat destruction in the wild.Species introduction that are invasive.Global warmingHunting and illicit trade.Thus the discovery of a buried crater (about 200 km across) near Chicxulub, Mexico.

Sort the steps of digestion in order from beginning to end.
- The stomach kills some bacteria and breaks food down into chyme.
- Nutrients from dissolved food are absorbed from the small intestine into the bloodstream.
- Water and nutrients are absorbed by the large intestine; chyme becomes waste matter.
- Saliva mixes with food and changes starches into sugars.
Saliva mixes with food and changes starches into sugars is the beginning step of the digestion.
What are the functions of saliva?Saliva is the medium that bathes the taste receptors in the oral cavity and in which aroma and taste compounds are released when food is eaten.
It is composed of water, mucus, proteins, mineral salts, and amylase. As saliva circulates in the mouth cavity it picks up food debris, bacterial cells, and white blood cells.
Saliva moistens the mouth for comfort, lubricates as you chew and swallow, and neutralizes harmful acids. It also kills germs and prevents bad breath, defends against tooth decay and gum disease, protects enamel, and speeds up wound healing.

which type of hormone diffuses across the plasma membrane and binds to receptors in the cytoplasm module 16.4c
Answer:
Steroid hormones.
Explanation:
Steroid hormones is a type of hormones that diffuses across the plasma membrane and binds to the receptors present in the cytoplasm. The hormones are released from the carrier protein and diffuse inside the cell across the lipid bilayer of the plasma membrane of the cells. The steroid hormones pass through the plasma membrane of a target cell and attached to the intracellular receptors located in the cytoplasm or in the nucleus.

why do wild plants need to reproduce sexually as well as asexually ?
Please answer correctly
Answer:
Wild plants would need to reproduce sexually so that there can be variation throughout the species to reduce the number of plants being at risks to certain diseases if the environment is changing. However, the wild plants need to produce asexually if the environment is stable.
Wild plants need to reproduce sexually as well as asexually in order to create variation within a species and lower the number of plants that are susceptible to specific illnesses in a changing environment.
What are wild plants?Wild plants would need to reproduce sexually. However, if the environment is stable, wild plants must reproduce asexually. Since male and female gametes are not mixed, asexual reproduction produces plants that are genetically similar to the parent plant and increases survival.
A seedling formed from a seed matures more slowly and is less robust than a cutting or bud is taken from an older plant.
Therefore, in order to diversify within a species and reduce the number of plants susceptible to specific diseases in a changing environment, wild plants must reproduce both sexually and asexually.

How does the experiment relate to what you've learned about submersible technology suck as submarines and ROV's?
Answer:
A submersible technology designed to operate the submarines underwater.
Explanation:
We have learned about submersible technology suck as submarines and ROV's is that pumping system is used to remove water from the submarines and ROV's in order to make it lighter. A submersible is designed to push water to the surface. When a pressure switch is turned on, the impeller started to spin drawing water into the pump. The water is then pushed through the pump and brought it to the surface. Due to removal of water, the submarines and ROV's become lighter and they will come to the surface of water.

Why has the number of people in the world increased if the human population growth rate has decreased?
Answer:
Life expectancy has steadily risen.
People live longer lives.
To understand the reasons why the number of people in the world has increased and the population growth rate has decreased, it is necessary to understand how the world's demographic growth rate is calculated.
The calculation is made from the balance between the total number of people alive and the total number of deaths that occurred in a period of time.
Therefore, we can understand that the population growth rate has decreased due to several relevant factors, such as:
Increased life expectancy.The decrease in infant mortality.Rising fertility rates.Urbanization.Economic development.These are some of the reasons that help us understand why population numbers increase and population growth rate decreases.
Economic development, new technologies and a better quality of life for the population are directly related to the decrease in the population growth rate.

If an area has very little permeability, such as a city where the ground is mostly concrete, what will happen to most of the rainwater?
A. It will become groundwater.
OB. It will be pumped into underground reservoirs by large machines.
C. It will become runoff.
D. The type of surface it falls on does not affect rainwater.
Answer:
C
Explanation:
The water won't be able to penetrate the ground so can't become ground water and reservoirs are usually above ground not underground so it will become run off.
Permeability is the ability of the substances to get diffused easily across the surface. The concrete ground results in the rainwater becoming runoff. Thus, option C is correct.
What is permeability?Permeability is the capacity of the water or any fluid to pass and diffuse across the substances or any membrane to get from the higher to lower concentration.
The concrete ground and roads are not permeable and do not allow water to pass through the material and effects the collection of the rainwater through infiltration.
The rainwater is unable to filter into the groundwater and becomes runoff. This runoff gets accumulated on the roads and can even lead to floods and drain blockages.
Therefore, option C. the less permeable roads cause rainwater to become runoff.

Some broad-spectrum proteases (protein hydrolyzing enzymes) and nucleases (nucleic acid hydrolyzing enzymes) that function in eukaryotic cells have an optimum pH close to 5.0, whereas the cytosol of most cells is closer to pH 7.0. Which part of a eukaryotic cell might you predict to have a low pH suited to maximizing the activity of these enzymes
Answer:
lysosome
Explanation:
The lysosome is a membrane-bound organelle found in nearly all eukaryotic cells. The lysosome contains different types of enzymes (i.e., proteases, nucleases, glycosidases, lipases, phosphatases) which are required for the digestion of macromolecules and microorganisms, and recycle macromolecules in the cell. These enzymes are only active in acidic (lysosome) conditions, and they can be deactivated in case of lysosomal rupture because in the cytosol the pH is neutral to slightly alkaline (∼7.3–7.4).
