Answer:
A plant cell.
Explanation:
Plant cells are part of multicellular organisms. They form tissues and are differentiated. If we see a section of plant cells, we can see that they have a box-like shape. This happens because plant cells, besides the membrane, are surrounded by a cell wall, which is rigid and gives the cell this form.
They also do photosynthesis, which is a metabolic process where they obtain energy from the radiation of the sun. To capture the photons they have pigments, especially a green pigment called chlorophyll. The chlorophyll is not free in the cytoplasm, it is contained in a bean-shaped organelle called chloroplast, and therefore they give the chloroplast this distinctive green color.
What molecules are involved in the oxygen cycle?
Answer:
In the atmosphere, the oxygen is mostly found as free O2 molecules released via photosynthesis. It also exists as ozone (O3), carbon dioxide (CO2), water vapor (H2O), and sulfur or nitrogen oxides.Explanation:

Scientists have discovered that the inner core of Earth is a solid while the outer core is a liquid. What is the cause of this observation?
A. The outer core has a higher temperature and more pressure than the inner core.
B. The outer care has lower temperature and lower pressure then the inner core.
C. The inner core has a lower temperature and higher pressure than the outer core.
D. The inner core has a higher temperature and lower pressure than the outer core.
Answer:Scientists figured out that the outer core must be liquid because S waves do not pass through it, but P waves do. The behavior of P and S waves also indicates that the inner core is solid. The speed of seismic waves also depends on the density of the material through which they are traveling.
Explanation:
The inner core of Earth is a solid which has a higher temperature and a higher pressure than the outer core of the planet. Thus, the correct option is C.
What is Earth's core?Scientists have discovered that the outer core of Earth must be liquid because of the S waves, which do not pass through it, whereas the P waves do pass through it. The behavior of P and S waves indicates that the inner core of Earth is solid. The speed of the seismic waves also depends on the density of the materials by which the waves are moving.
The pressure of the inner core is nearly 3.6 million atmosphere and the temperature of the inner core is far above the melting point of iron element. However, the inner core is solid. The inner core's intense pressure and temperature than the rest of the planet prevents the iron from melting.
Therefore, the correct option is C.

how would the pattern of apoptosis differ in a duck’s webbed foot compared to the pattern of apoptosis in a mouse’s foot? Explain
Answer:
A duck's foot is webbed and the chicken's foot is not
Explanation:
The difference is due to apoptosis.Ducks have webbed feet because the cells between their toes do not undergo apoptosis
Apoptosis is a form of programmed cell death. It is the result of the self-destruction mechanisms that is started when the cells respond to a certain stimulus that leads to the destruction of the cell.
The duck's foot is webbed and chickens food is not a sign of swimming ability. The ducks have webbed feet as their foot don't undergo apoptosis. Hence they have webbed.Learn more about the apoptosis that differs in a duck’s webbed foot.

how is carbon moved through the carbon cycle through the process of photosynthesis and cellular respiration
Answer:
Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.

Explain how the Naked DNA exploits vector's DNA ability to make a vaccine.
Answer:
DNA vaccines consist of DNA vectors or plasmids (small double-stranded DNA rings originally derived from bacteria, but unable to cause infection) into which the genes encoding one or more immunizing proteins of the infectious agent have been inserted causing the disease to be prevented.
Explanation:
Vectors are the functional unit of naked DNA vaccines. Genes that encode the proteins of interest and are of bacterial origin are inserted into these vectors. Bacterial plasmids are circular DNA molecules that self-replicate extrachromosomally in bacteria. The genes encoded in these plasmids are under the control of promoters, almost always of viral origin. When a plasmid is introduced into the cell it translocates to the nucleus, where transcription of the transgene begins; the transcripts are then taken to the cytoplasm and translated there. The newly synthesized proteins are degraded in the proteasome to 8-10 amino acid peptides, which are transported to the endoplasmic reticulum. Peptides of high affinity with their respective MHC I molecule stabilize and enter the secretory pathway, thus reaching the cell surface, where they are coupled with the T-lymphocyte receptor (TcR) present on the surface of T lymphocytes cytotoxic drugs (CD8 +) to induce their activation.

What is the relationship between water clarity and orca survival?
Answer:
Direct relationship.
Explanation:
There is a direct relationship between water clarity and orca survival because the survival of orca depend on the quality of water. If the water quality is good and clean, the orca survival rate increases whereas if the water quality decreases due to pollution, the orca survival also decreases. The chemicals drained into the water bodies is the main cause of lowering orca survival rate so we can say that both have direct relationship.
There is a direct relationship between water clarity and orca survival because, the clearer the water, the higher the survival rate of orca.
Note the following about Water Clarity and how it affects aquatic life:
Water clarity refers to the measure of how deep light can penetrate through water.Suspended particles and soil on water can reduce the level of light penetration in aquatic ecosystem.Light is needful for the growth of aquatic plants, which produce oxygen for other aquatic.Aquatic plants also provide habitat for fish and other aquatic life like the orca.Clearer waters promote growth and survival for aquatic life including the orca.Therefore, there is a direct relationship between water clarity and orca survival because, the clearer the water, the higher the survival rate of orca.

what is the function of ovary
Answer:
The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
The period when humans first domesticated plants and animals is known as the:
a. Domestic revolution
b. Neolithic revolution
c. Paleolithic revolution
d. Tribal revolution
During Neolithic revolution first domesticated plants and animals began. Thus, option B is correct.
What is Neolithic revolution?Thousands of years before humans survived on hunting and gathering practices before crops were developed. Hunter gathers were highly migratory and mobile, lived in small tribes. They were highly depended upon what environment could provide each season.
The first agricultural revolution began called as Neolithic revolution, which helped to form lager populations by changing lifestyle of hunting into agriculture and settlement.
Therefore, Neolithic revolution is the period when humans first domesticated plants and animals.

13. Which of the following would most likely consume a dead rabbit?
O Carnivore
O Detritivore
Herbivore
O Omnivore
Answer: Detrivore
Explanation: Detritivores are a smaller, narrower branch of decomposers that break down dead organic matter by consuming it, like worms. Scavengers, on the other hand, only eat some of the dead animal, but cannot break down the entire carcass, like the bones and feathers (I know that's not the question, but it may help to know the difference). Carnivores are animals that only eat the flesh (meat) of other animals, like a blue whale, which feeds on krill. Herbivores only eat plants, or herbs, like zebras. Omnivores, like humans in general, eat both plants and animals.
