1. Explain the function of white blood cells in the body.
2.
How is a red blood cell adapted to carry
oxygen and nutrients throughout the body? Explain
3.
What would happen to us if no platelets
are found within the blood again. Explain.
4. Give the general (collective) functions of the blood
Answer:1. White blood cells are part of the body's immune system. They help the body fight infection and other diseases.
2. Red blood cells have adaptations that make them suitable for this.
3. The blood would not clot in case of an injury.
4. Blood supplies essential substances and nutrients.
Explanation: 1. White blood cells are able to recognize viruses and/or infectious germs, which is how they fight off disease/sickness. It is also why we have vaccines. Vaccines put either dead or weakened parts of a germ into your body. Then, the white blood cells recognize it and fight it off the next time it enters your body.
2. They contain hemoglobin, a red protein that combines with oxygen. They have no nucleus so they can contain more of the hemoglobin. they are small and flexible so that they can fit through narrow blood vessels.
3. This will lead to excess blood loss and can even lead to the death.
4. Such as as sugar, oxygen, and hormones to our cells. It also carries waste away from the cells, this waste is eventually flushed out of the body in urine, feces, sweat, and lungs.

*What is the relationship between DNA and gene expression? How do they depend on each other?*
Answer:
Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. When the information stored in our DNA? is converted into instructions for making proteins? or other molecules, it is called gene expression
Explanation:
DNA makes genetic expression. DNA is a structure located in the nucleus that makes people themselves. DNA is unique to everyone, no two people are exactly the same. The way the DNA is structured and what instructions it was given affect one's genetic makeup.

What do you mean by cells?Cell is the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm.
Moreover, they provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function.
There are two main types of cells: prokaryotic cells and eukaryotic cells. Prokaryotic cells include bacteria and archaea. Prokaryotes—organisms composed of a prokaryotic cell—are always single-celled (unicellular). Prokaryotic cells don't contain a nucleus.

Phenomenon: Miss Westbrook visited family in Aspen last spring. Aspen is in Colorado and has an elevation of 8,000-9,000 feet. The Bay Area has an elevation of 0-100 feet. Miss Westbrook’s breathing and heart rate both sped up every time she went hiking or skiing in Aspen. Why do you think this happened?
Hint: Your brain regulates the rate and depth of your breathing to match the needs of your body for 02 intake and CO2 removal.
Breathing rate refers to the number of breaths per minute.
This happened due to the low air pressure in the highest areas of Colorado, which made hard the intake of air.
Air pressure is fewer as the elevation in an area increases. In other words, the air over us is less, so the pressure that it makes is lower.
Miss Westbrook's heart rate and breathing sped up due to the low air pressure that she experimented with when ascending or when skiing in Aspen, which is very elevated. As the pressure is lower, not much air can enter the lungs, so her brain increases the breath rate to obtain the same amount of oxygen that her body had when breathing normally on the Bay. As there is not enough oxygen in her body, the brain also increases the heart rate to match the rhythm of the breath and deliver the scarce oxygen to the different parts of the body.
In conclusion, the increase in the heart and breath rate happens due to the low air pressure in elevated areas that makes our body find ways to compensate for the decrease in the amount of oxygen that our body can take.

How do coral reefs help with climate stability?
They need vast amounts of carbon dioxide for energy.
They support mangroves and seagrasses that release carbon.
They are habitats for species that build exoskeletons from carbon.
They release atmospheric carbon that organisms use to live and grow.
The coral reefs help with climate stability because they serve as homes for species that build exoskeletons from carbon.
Carbon in the form of carbon dioxide has been reported to be a major factor in the climate instability of the planet. This is because they are parts of the greenhouse gases that form a blanket layer over the atmosphere and prevent reflected sun rays from escaping back to space.
Thus, greenhouse gases cause the earth's atmosphere to warm up, a phenomenon known as global warming. The warming, in turn, leads to the unpredictability of several climatic factors.
With the majority of the species living in coral reefs helping to make use of carbon dioxide to build their exoskeleton, they are helping to reduce the concentration of the gas in the atmosphere and thereby reducing warming and erratic climatic changes.

What is an angiosperm? Provide 2 examples. PLEASEE
Answer: Angiosperms represent approximately 80 percent of all known living green plants. Examples range from the common dandelion to ancient flowers such as magnolias. Angiosperms also make up the vast majority of all plant foods we eat. (Ex. grains, vegetables, and fruits.) The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary The ovary itself is usually enclosed in a flower, that part of the angiospermous plant that contains the male or female reproductive organs or both. fruits are derived from the maturing floral organs of the angiospermous plant and are therefore characteristic of angiosperms.

A child watches an older sibling playing with a ball but makes no effort to participate in the play. Which social character is the child exhibiting
Answer:
Onlooker play
Explanation:
In onlooker play a child actively observes other children playing and does not attempt to enter into the activity; the child is interested only in observation and not in participation. In parallel play children play independently among other children. In pretend play children act out any event of daily life and practice the roles and identities as established in their surroundings. In associative play children play together and are engaged in a similar or identical activity.
3. What challenges do older generations face?
Answer:
Health problem. As aging occurs, the more weak and unstable the body gets.
Unporportionate generation distribution. Some older generations are larger than the ones that precede it, thus, making it harder to have the proper resources to take care of older generations.
Technology. It is harder for older generations to be up-to-date on technology. This can make it harder for older generations to function in society properly.

Describe what would occur if you turned a growing seedling on its side (without disturbing the root system.) What is occurring inside the plant, and what hormone is involved? Be specific.
Phytohormones are responsible for the movement of plant towards stimulus. Auxin is the main phytohormone responsible for gravitropism and phototropism of plants.
What is Plant Movement?Plants are immobile however different parts of the plant show movements in response to the stimulus in the environment. The chemicals present in the plant body which are responsible for these movements are called phytohormones or plant hormones.
Auxins are the main hormones responsible for the cell elongation in plants. Auxins are responsible for the phototropism (movement of plant parts in response to light) and gravitropism (movement in plants in response to gravity).
Roots of a plant grow downward and exhibit positive gravitropism whereas stems on the other hand, exhibit negative gravitropism since they grow upwards and against the gravity. If you place a plant on its side or even upside down, the stem will curve its way up in response to gravity and auxin is responsible for this movement.

What kind of trait is dimples?
Hereditary characteristics can be either dominant or recessive, as is the case with humans . Chromosome 5 is thought to be the location of the dominant gene responsible for the inheritance of cheek dimples, while chromosome 16 is thought to be the location of the dominant gene responsible for the inheritance of chin dimples.
It is generally accepted that dimples are caused by a dominant genetic feature, which indicates that the presence of only one mutated copy of a gene in each cell is required to produce the trait. On the other hand, there are academics who argue that there is no evidence to support the theory that dimples are inherited.
