Answer:
Lateral gene transfer allows the bacteria to develop resistance to antibiotics and spread it between bacterial populations. ... This process allows bacteria to transfer genes from one population into another. As a result, the next generation would evolve and develop defenses that would make them resistant to the drug.
Explanation:
An adult hemopoietic stem cell found in the bone marrow ______________________. (a) will occasionally produce epidermal cells when necessary. (b) can produce only red blood cells. (c) can undergo self-renewing divisions for the lifetime of a healthy animal. (d) will express all the same transcription factors as those found in an unfertilized egg.
Answer: (c) can undergo self-renewing divisions for the lifetime of a healthy animal.
Explanation:
The adult hematopoietic tissue or adult hematopoietic stem cells can be found in bone marrow of the animal. These cells have the ability to regenerate and renew so that the production of red blood cells remains continuous till death. Hematopoiesis can be defined as the production of cellular components of blood. The adult hematopoietic stem cells are located in the flat bones and ends of the long bones.
define the process of photosynthesis
Answer:
The process by which the green plants prepare their food in presence of sunlight , water and carbon dioxide is called photosynthesis.
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Which of the following explains the conservation of mass during cellular respiration? (4 points) a The total number of atoms when carbon dioxide and oxygen react stays the same when glucose and water are produced. b The total number of atoms when water and oxygen react stays the same when glucose and water are produced. c The total number of atoms when carbon dioxide and water react stays the same when glucose and oxygen are produced. d The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced.
Answer:
D- The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced.
Explanation:
The conservation of mass during cellular respiration can be explained by the fact that after cellular respiration which occurs due to the oxidation of glucose to produce carbon dioxide and water, the number of atoms on the right hand side (RHS) of the reaction remain same as of left hand side (LHS) of the reaction.
The balanced chemical equation is mentioned as under:
C₆H₁₂O₆ + 6 O₂ -> 6 CO₂ + 6H₂O + Energy.
(Glucose) (Oxygen) (Carbon (Water)
dioxide)
If we will see carefully, the number of atoms of each element on RHS & LHS of the equation are same i.e. there are 6 atoms of C, 18 atoms of O and 12 atoms of H on both the sides.
Carrying capacity is Group of answer choices seldom reached by marine producers and consumers because of the vast resources of the ocean. the maximum population size that a particular environment can support. fixed for most species over most of their range most of the time. the term used to describe the stress a population undergoes due to limited resources.
Answer:
the maximum population size that a particular environment can support.
Explanation:
A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.
Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.
Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;
I. Density-independent factors.
II. Density-dependent factors.
Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.
Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.
Carrying capacity is the maximum population size that a particular environment can support. The carrying capacity of an environment is denoted by the letter k.

Explanation:
Which substance keeps its shape, weight, and volume when it is moved to a bigger container?
Answer:
Wood
Explanation:
Unless kept in a confined space, oil, are, and water will all naturally deform out of their previous shape when transferred to another container. Wood, on the other hand, is a solid, which means it will stay in it's shape.

What is resource partitioning and how is it an adaptation to competition? Provide an
example.
Definition:
Resource partitioning is the division of limited resources by species to help avoid competition in an ecological niche.
In any environment, organisms compete for limited resources, so organisms and different species have to find ways to coexist with one another.
Example:
Some lizard species appear to coexist because they consume insects of differing sizes.

What are four examples of learned behaviors in animals?
Answer:
Habituation. Sensitization. Classical conditioning. Operant conditioning.Explanation:
Types of learning include habituation, sensitization, classical conditioning, operant conditioning, observational learning, play, and insight learning. One of the simplest ways that animals learn is through habituation, where animals decrease the frequency of the behavior in response to a repeated stimulus.

what are the components of the atmosphere that help organisms live on earth?
EXPLAIN and I will make you brainliest!!!
Answer: Atmospheric gases, especially carbon dioxide (CO2) and oxygen (O2), are extremely important for living organisms. Carbon dioxide and oxygen are the gases in the atmosphere that are needed for life. Plants need carbon dioxide for photosynthesis. They use sunlight to change carbon dioxide and water into food. The process releases oxygen

What is happening to the [OH-] when the solution turns from pink to violet?
Answer:
the hydroxide ions are undergoing ionization and the particles are gaining / losing electrons .
Explanation:
i think it is because ::
the phenolphthalein of the solution has gone from having a pH of around 8 (pink) to being alkaline at above 10 which causes it to burn purple / violet .
1. This question may be completed independently or as a group exercise. Biological anthropologists disagree about the best way to classify the robust australopithecines. Describe the two approaches to classifying these species. Which classification do you support
Answer:
Some researchers classify Australopithecines into gracile australopithecines and robust australopithecines, while others argue that differences are enough strong to classify robust australopithecines in their own genus called 'Paranthropus'. In my opinion, it seems reasonable to obtain more fossil data in order to support this division
Explanation:
The term Australopithecines comes from the genus Australopithecus, which are the closest known relatives of our genus Homo, and arose around three (3) million years ago. Australopithecines can be classified into two major groups called gracile australopithecines and robust australopithecines. However, robust australopithecines have also been classified in their own genus, Paranthropus, in order to distinguish them from the gracile australopithecines. The major differences between gracile and robust species are associated with facial and cranial features. Paranthropus species had a large sagittal crest, enormous cheek teeth, robust jaws, and strong jaw muscles (suggesting they were herbivores that ate tough food). However, these main features may not be conclusive evidence that supports the separation of Paranthropus in its own clade, thereby in my opinion it should be reasonable to wait until more fossils are found in order to correctly classify Paranthropus species as a different group.
