Answer:
The innate immunity in living organisms protects them from the pathogens they encounter daily.
Explanation:
Pathogens are organisms such as virus, fungi, bacteria, protozoa, worms that causes diseases to its host.
For example, Avian flu is a strain or variant of the Influenza virus which predominantly causes a disease in birds such as chickens. The virus responsible for the Avian flu can be passed from birds to humans; when anyone comes in contact with a bird that is carrying the virus i.e a sick bird with Avian flu.
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.
Also, immunization can be defined as the process of boosting an individual's immunity or immune system against antigens (immunogen) which cause diseases by the administration of vaccines.
Basically, immunization helps to improve the functions of the antibodies, B cells, T cells etc.
If a person becomes infected with a pathogen, such as a virus. The internal stimulus that mainly 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).
A mother and father both have brown eyes, but their child has blue eyes. Which statement most likely explains this
Answer:
Blue eyes is a recessive trait
Explanation:
Recessive traits show in 25% of the offspring, but they skip the first generation. This means that the 25% only shows up in the second generation unless two recessive traits are put together. A likely combination is that both of the parents had Bb, which you can put into a punnet square to visualize.
B b
B BB Bb
b Bb bb90

w, use what you have learned about heredity to complete the chart below. The allele pairs in the left column represent eye color in fruit flies. Ris the
ominant color (red), and r is the recessive color (white). Study the chart and fill in the missing phenotypes.
Answer:
RR is hom0zygous dominant and will Red
Rr is heterosygous and will also be red
rr is hom0zygous recessive and will be white
Explanation:
The filling of the chart with respect to the genotype given is as follows:
RR (homozygous dominant) gives Red eye color in fruit flies. Rr (heterozygous) will also deliver red eye color in fruit flies.rr (homozygous recessive) gives white eye color in fruit flies. What is meant by Genotype?Genotype may be defined as the ultimate combination of alleles of those genes which are selected for specific study in order to deliver some sort of genetic information.
As it is an organism is its complete set of genetic material. These can also be utilized in order to refer to the alleles or variants an individual carries in a particular gene or genetic location.
In fruit flies, red eye color is dominant over white eye color. So, when red eyed-colored (RR) flies are crossed with white-eyed colored flies (rr), they produce offspring with the genotype Rr and phenotype of red-eye color. This all deals with the law of dominance.
Therefore, the filling of the chart with respect to the genotype given is well described above.

4. What are two ways that celestial navigation/astronavigation and navigation by GPS differ?
Do they have anything in common?
Differences: Celestial navigation is completely based on the position of sun in the sky. Here, the use of angular measurements can exist among the celestial objects. It is less accurate than the GPS.
The ways that celestial navigation/astronavigation and navigation by GPS differ include:
Celestial navigation is less accurate than GPS.Celestial navigation is an ancient method of navigation while GPS is a newer method of navigation.Celestial navigation is the navigation by the sun, moon, stars, and planets. GPS which refers to the global positioning system refers to the navigation system that's space-based that is important for broadcasting accurate navigation pulses to the users.The global positioning system is also known to be the network of satellites that are used in determining the location of a particular thing.The similarity between them is that they are both ways of locating a particular thing since they're used for navigation.Read related link on:

Answer:
Kindly refer to the attachment.Thank U,NExt
DNA can be used to tell people apart - their DNA sequences or the lengths of repeated regions of DNA
Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique.
DNA contains genetic information that is passed from adult organisms to their offspring during reproduction.Each offspring forms by the combination of the parent's gene or DNAThe actual sequence of DNA on each of the chromosomes is unique due in part to recombination.recombination causes genetic variation and made everyone unique.This is incorporated in the nucleotide sequences in DNA molecules.Thus, DNA can be used to tell people apart - their DNA sequences or the lengths of repeated regions of DNA

Complete the flowchart to show the stages of cellular respiration and fermentation.
Cellular Respiration and Fermentation
Answer:
The stages of cellular respiration are: Glycolysis, pyruvate oxidation, Krebs cycle and phosphorylative oxidation.
The fermentation stages are: glycolysis and pyruvate regeneration.
Explanation:
Cellular respiration is a biochemical process that occurs in all aerobic organisms and aims to promote the obtaining of the necessary energy so that the cells can perform the activities they need to perform. Cellular respiration occurs in mitochondria and oxygen must be present in the process.
Fermentation is the biochemical process that replaces cellular respiration in organisms that do not survive in the presence of oxygen, the anaerobic organisms that are some fungi and bacteria. Fermentation also aims to produce cellular energy.

D. Transporting eggs
WILL MARK BRAINLIEST!!
Answer:
the picture isnt really clear but i guess B
Explanation:
just to explain the collecting of sperm happens in the oviduct
the developing of a fetus happens in the uterus
The female reproductive system includes the glands and organs that produce the female gamete, the egg. The highlighted part in the diagram stores eggs. Thus, option C is correct.
What are the parts of the female reproductive system?The female reproductive system has various organs like ovaries, fallopian tubes, vagina, uterus, accessory, and other external organs. They are involved in the production and storage of eggs or the ovum.
The ovaries are the main organs that are two in number and oval-shaped structures, located on either side of the uterus, and produce ovum and hormones, estrogen and progesterone.
During the menstrual cycle, one of the ovaries releases the ovum in the fallopian tubes that may get fertilized or get shaded with the blood and tissues. The egg is produced through the process of oogenesis in the ovaries.
Therefore, the highlighted part is the ovary that stores the egg.

Imagine yourself as a naturalist. In your travels, you observe the toad and frog
shown here. Write two questions that might arise from these observations.
Answer:
1. What is the relationship between body shape and the habitat where they are most commonly found?
2. What is the difference between toads having a thicker skin than frogs?
Explanation:
Toads and frogs are amphibians that belong to the same family, live in lakes, rivers and wetlands and have some similar characteristics. Among their main differences are:
The skin of toads is rougher, drier and rougher. While frog skin is moist and smooth. Frogs live in humid areas, although they can go out to dry land for food. Whereas toads can survive longer on the ground away from moisture, as they have greater water control in the body. Frogs are characterized by long limbs that favor long hopping and swimming. On the other hand, toads have shorter legs. Toads tend to be more rounded, muscular and stocky. Frogs tend to be more slender.Most toads are poisonous. In contrast in frogs, not all species are poisonous.
Given these observations, two questions that may arise could be:
1. What is the relationship between body shape and the habitat where they are most commonly found? This is that frogs have longer legs which helps them to swim and that is why they are more commonly found in water. While toads have shorter legs that even allow them to burrow into the ground, they can survive longer on land.
2. What is the difference between toads having a thicker skin than frogs? Toads have thicker and more impermeable skin than frogs, which allows them to live in drier places. Also, the blood of the toad is of higher osmotic concentration than water.
Answer: what is the difference between the body’s and the habitat they are in?
Explanation:both have similar habitats and look the same
