HELP!! I'm struggling!!

Answer:

They are eukaryotic cells, they present the three main parts: cell or cytoplasmic membrane, cytoplasm and nucleus defined with chromosomes and nucleolus. The three types of cells have in common the following structures: cell membrane, cytoplasm, nucleus defined with chromosomes and nucleolus, mitochondria, smooth and rough endoplasmic reticulum, ribosomes, Golgi apparatus, cytoskeleton and peroxisomes. But it differs in some. The plant cell has chloroplasts and a cell wall and the animal cell does not.

Explanation:

The animal cell has centrioles, lysosomes. It has no plastids, no cell wall, it has vesicles. They do not have the ability to produce their own food from inorganic components. The plant cell has plastids (chloroplasts), cell walls, large vacuoles. Fungal cells are organisms without chlorophyll, therefore they cannot photosynthesize. The reserve substances of the cytoplasm are not starch granules. As they are not able to synthesize their food, they have to obtain from other living organisms (they feed on other plant and animal residues contributing to decomposition) that is, they are heterotrophic. Fungal cells have a cell wall that is not present in animal cells and but plant cells have a cell wall. They have lysosomes and centrioles that the plant cell lacks but they are in animal cells. Animal cells, with a few exceptions, do not have vacuoles while plant cells do. The three types of cells have present nucleus, membrane, mitochondria, endoplasmic reticulum, Golgi system.

Answer:

By consuming necessary amount of calcium per day.

Explanation:

The amount of calcium is recommended for adults are 1000 mg per day whereas for aged people, it should be 1200 mg per day and for children it becomes 1300 mg per day in order to make the bones stronger and avoid the risk of fracture. The risk of bone fractures can be changed by consuming the recommended amount of calcium through your diet.

Answer:

B. Their core temperature increases.

Explanation:

Pathogens are organisms such as virus, fungi, bacteria, protozoa, worms that causes diseases to its host.

Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.

If a person becomes infected with a pathogen, such as a virus. The internal stimulus that most likely takes place in order for their body to maintain homeostasis is that their core temperature increases. This is because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).

Additionally, in order to reduce pathogens and prevent illness, it is very important to cook our food to high degrees of temperatures. These pathogens are usually destroyed by heat, so it's necessary and important to properly cook food to a high temperature by grilling, boiling, frying, roasting and baking. Also, a hot-holding unit can be used to store food in order to reduce pathogens.

If you take a look at evolution on Earth, 99.9 percent of all life forms have gone extinct. When things change, either you adapt or die. That’s the law of Mother Nature. We face various hazards. First of all, we have self-inflicted problems like global warming, nuclear proliferation and bio-engineered germ warfare. Plus, Mother Nature has hurled at the Earth a number of extinction cycles. The dinosaurs, for example, didn’t have a space program. And that’s why the dinosaurs are not here today.

                                           The Rock Cycle

                                      by _________________

The rock cycle is a process in which rocks are continuously transformed between the three rock types igneous, sedimentary and metamorphic .Conversion to metamorphic rocks requires conditions of increased temperature and/or increased pressure, conversion to sedimentary rocks occurs via the intermediate stage of sediments, and conversion to igneous rocks occurs via the intermediate stage of magma. Increased temperature and pressure occurs in subduction zones and in areas where two plates of continental lithosphere collide to produce a mountain range, while increased pressure without increased temperature is produced when sedimentary rocks are deeply buried under more sediments. Sediments are produced when rocks are uplifted, weathered and eroded, and the resulting detrital material deposited in marine or terrestrial basins. If the sediments are buried under further layers of sediment, they can become lithified to produce a sedimentary rock. Magma is produced when rocks are melted. This melting can occur when a lithospheric plate descends into the Earth’s crust at a subduction zone, or when a mid-ocean ridge opens up and produces decompression melting in the athenosphere under the ridge. When the magma solidifies, it becomes an igneous rock.

The rock cycle has many alternative pathways. The following diagram illustrates one of these and gives an indication of the plate tectonic setting where it occurs:

Answer:

No, it is not possible

Explanation:

Humans use the ABO blood group system where the A and B alleles are dominant over allele O but codominant with one another.

This system is such that;

Type A can only have genotype: iAiA or iAi

Type B can only have genotype: iBiB or iBi

Type AB can only have genotype: iAiB

Type O can only have genotype: ii

According to this question, a woman has blood Type A (iAiA or iAi) and her baby has blood Type AB (iAiB). This means that the father definitely contributed the allele B in order to have a baby with type AB. It also means that, according to the question, IT IS NOT POSSIBLE FOR A "Type A" father to produce that baby (see the punnet square attached).

Note: The father must contain an allele B in his genotype i.e. the father must be either type B (iBiB or iBi) or type AB (iAiB)

Answer:

See the answer below

Explanation:

Let us assume the sickle cell anemia allele to be S and the alternate, non-sickle cell allele to be A.

Since the woman has no history of sickle cell in her family, she is totally free from the trait and, hence, would have the genotype of AA.

The man's father had sickle cell anemia. This means that the man has, at least, one sickle cell allele in his genotype with the other allele depending on the genotype of his mother. Hence, the man can be AS or SS depending on the genotype of his mother.

Answer:

Plants and animals need sugar called glucose in order to make instant energy (ATP) in a process called cellular respiration (photosynthesis for plants)

Explanatio

For example, hydrogen atoms are fused together to form helium. In the process, an immense amount of heat and energy is released. Much of that energy is on the electromagnetic spectrum that we cannot see (eg: ultraviolet light), but the visible portion of the spectrum is what we can see and that produces the yellow glow of the sun.

False.

Gravitropism ensures that roots grow into the soil and that shoots grow toward sunlight. Growth of the shoot apical tip upward is called negative gravitropism, whereas growth of the roots downward is called positive gravitropism.

Answer:

a) There are a number of types of asexual reproduction including fission, fragmentation, budding, vegetative reproduction, spore formation and agamogenesis. Spore formation occurs in plants, and some algae and fungi, and will be discussed in additional concepts

b) The advantages of sexual reproduction:

.) produces genetic variation in the offspring.

.) the species can adapt to new environments due to variation, which gives them a survival advantage.

.) a disease is less likely to affect all the individuals in a population.

c) The disadvantages of asexual reproduction include:

.) it does not lead to genetic variation in a population.

.) the species may only be suited to one habitat.

.) disease may affect all the individuals in a population.

d) the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female).

e) each of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

f) Sexual reproduction gives rise to more viable variation than asexual reproduction. Because in sexual reproduction, genetic material from both the parents mixed (recombination of parent chromosomes) by fertilization...
