In eukaryotes, cellular respiration takes place in the(1 point)
mitochondria.
nucleus.
cytoplasm.
cellular membrane.
Answer:
mitochondria
Explanation:
Aerobic respiration is characteristic of eukaryotic cells when they have sufficient oxygen and most of it takes place in the mitochondria.
In eukaryotes, cellular respiration takes place in the mitochondria.
WHAT IS CELLULAR RESPIRATION:Cellular respiration is the process whereby living organisms obtain energy in form of ATP by breaking down food molecules in their cells. Cellular respiration occurs in the mitochondria of eukaryotic cells but in the cytoplasm of prokaryotic cells. The mitochondria is a double membrane organelle commonly termed the power house of the cell because of the supply of ATP.Therefore, in eukaryotes, cellular respiration takes place in the mitochondria.

Could you explain the roles and relationships among producers, consumers, and decomposers, and identify the distinguished characteristics of several common relationships among organisms in an ecosystem near you?
Answer:
A consumer may also eat other consumers as food. When producers and consumers die, the Decomposer will come along to decompose (break down) the bodies of the dead producers and consumers into smaller chemicals - in short treating them as a food source
Explanation:
Your welcome have a good day :)
The producers, consumers, and decomposers are related to each other in an ecosystem in a specific way.
What is an Ecosystem?The interaction between the organisms of different species plays their role in a systematic way as decided by natural selection, which is known as the Ecosystem.
Producers use light energy and inorganic matter to produce food. They are always present first in the ecosystem. Consumers take energy from plants known as herbivores, and also from herbivores known as Carnivores. Decomposers convert dead organic matter into inorganic matter. This inorganic matter helps producers perform metabolic activities. And finally, this cycle goes on.
Therefore, the producers, consumers, and decomposers are related to each other in an ecosystem in a specific way.

HURRY QUICK 28. An herbicide killed 99% of a weed population. Which of the following is the BEST
biological explanation for why some weeds were able to survive? (1 point)
O Some individuals were able to evolve before the spraying.
Each individual occupied a different ecological niche and so some were unaffected.
Genetic variation in the population allowed some weeds to survive.
The spray caused some individuals to mutate, and they were able to survive and
reproduce.
Answer:
Genetic variation in the population allowed some weeds to survive
Explanation:
Herbicides are substances that are used to destroy unwanted plants. Herbicides are also called weed killers. An herbicide killed 99% of a weed population.
Some weeds were not able to survive as genetic variation in the population allowed some weeds to survive.

Answer: Two parents, one with type B blood and one with type A blood.
Explanation: They both have different blood types, so that leads to the child having an O blood type.
Hope this helps!!
Sorry if it's wrong!!
Have a great day!!
If the two parents have blood group A and blood group B with their child of type O blood. Then, the possible genotypes of the parents is AO and BO. Thus, the correct option is A.
What is Blood group?A blood type is the classification of blood. Classification of blood group is based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells. These antigens are biomolecules which may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system.
There are four main blood groups which are A, B, AB and O. Blood group is determined by the genes a person inherit from the parents. In a cross between one parent with blood type A and one with blood type B having child with blood type O has genotypes AO and BO. The genotype is shown in the punnett square.
Therefore, the correct option is A.

Analogy and homology are important concepts used in comparing species. Traits are homologous if they are derived, evolutionarily and developmentally, from the same source structure. Traits are analogous if they have similar functions but are derived, evolutionarily and developmentally, from different source structures. A classic example of analogous structures is insect wings and bat wings. Which of the following pairs of structures are analogous and which are homologous?
a. Dorsal fins of porpoise and a salmon
b. Flippers of porpoise and pectoral fins (front fins) of salmon
c. Joined leg of ladybird beetle and a robin
d. Rhesus monkey's tail and human's coccyx
e. Bright red bracts of poinsettia and green leaves of rose
f. Red bracts on a poinsettia and red petals on rose
Answer:
a. analogous
b. homologous
c. analogous
d. homologous
e. homologous
f. homologous
Explanation:
a. Analogous. Porpoises are mammals while salmon are fish. In this case, fins are analogous structures that evolved separately in both groups.
b. Homologous. Pectoral fins evolved from the forearms of tetrapods, and early tetrapods evolved from fish.
c. Analogous. These structures evolved independently through convergent evolution in both groups.
d. Homologous. They are homologous structures that were inherited from a common ancestor (primates).
e. Homologous. Bright red bracts (modified leaves) of poinsettia and green leaves of rose share a common ancestor (i.e., angiosperms).
f. Homologous. They are homologous structures that were inherited from a common ancestor (i.e., angiosperms).

Answer:
This is the site of gaseous exchange
Explanation:
Gaseous exchange is the mechanism by which oxygen is substituted for CO₂ in the body. CO₂ laden blood is carried to the alveoli, which is wrapped with numerous capillary beds and with walls that are thin. When a person inhales, the difference in the partial pressure of the various gases ( oxygen and carbon dioxide) causes them t move down their concentration gradients, with CO₂ diffusion into the lungs from red blood cells, and oxygen binding to the haemoglobin in the red blood cells, after which they are carried to all body tissues for cellular respiration. During exhalation, the CO₂ in the lungs is expelled to the exterior and the process repeats.

How do animals and people get glucose?
Answer:
Animals obtain glucose by eating plants, and fungi and bacteria absorb glucose as they break down the tissues of plants and animals.
And for humans it mainly comes from foods rich in carbohydrates, like bread, potatoes, and fruit. As you eat, food travels down your oesophagus to your stomach. There, acids and enzymes break it down into tiny pieces. During that process, glucose is released.

Answer:
heterozygous
Explanation:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene. Genotypes are described as heterozygous if the two alleles differ.
