Imagine that there is a loss-of-function mutation in the gene for the Notch receptor in the progenitor cell of C. elegans. How does that mutation affect vulva development
Answer:
Hello your question is incomplete attached below is the complete question
answer :
None of the progenator cells differentiate into type 2 cells. ( A )
Explanation:
Due to the loss-of- function mutation in the gene for the Notch receptor in the progenitor cell of C elegans , This causes The progenator cells for type 1 to be differentiated to type 1 cells but the cells for type 2 will not be differentiated.
hence the answer is : None of the progenator cells differentiate into type 2 cells.
 True or False: If two organisms are located near one another on a phylogenetic tree they share a recent common ancestor.
HELP ILL MARK BRAINLIEST!
Answer:
True
Explanation:
When are the two organisms that share the most common ancestor in the tree 1. the sequence of branching does not necessarily indicate the actual (absolute) ages of the particular species 2. we cannot assume that a taxon on a phylogenetic tree evolved from the taxon next to it (just bc two species are located near each other does not mean the are more clostly related)
“Phylogenetic relationship” refers to the relative times in the past that species shared common ancestors. Two species (B & C) are more closely related to one another than either one is to a third species (A) if, and only if, they share a more recent common ancestor with one another (at Time 2) than they do with the third species (at Time 1).
Which statement is accurate about natural selection?(1 point) A. Natural selection cannot inactivate genes. B. Natural selection does not impact reproduction rates. C. Natural selection does not change the alleles an organism has. D. Natural selection cannot occur through mutations.
Answer:
B
Explanation:
The correct option is "B" Natural selection does not impact reproduction rates according to the theory of Natural selection.
What are the factors of natural selection?Natural selection is the process through which populations of living organisms adapt and change. There are four factors are required for natural selection are reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population.
Hence, the option is "B" Natural selection does not impact reproduction rates according to the theory of Natural selection.

The ecosystem with the greatest sustainability will be the one that has the
Answer:
Different organisms or animals
Explanation: In a ecosystem, if you have different animals or organisms, it give them a better chance of survival, reason being that they can choose to eat whatever animal or organism they want because there is lots of animals to choose from the ecosystem. Basically the more diversity you have, the better chance you will survive, and the less diversity you have, the less chance of survival.
What does it mean to ‘translate’ something? What is being translated in protein synthesis?
Answer:
Answer:
Translation is the process of translating the sequence of a messenger RNA molecule to a sequence of amino acids during protein synthesis. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding amino acid sequence that it encodes.
For a second i thought you meant to translate something to another language lol.
Bacteria Natural Selection
Answer:
Bacterial resistance arises through the simple process of natural selection. Bacteria divide rapidly, but DNA replication is imperfect. In the presence of antibiotics, while most bacteria are killed, a small number of resistant mutants may survive and take over.
Explanation:
List and describe the three major theoretical issues in the study of lifespan development.
Explanation:
Three issues pervade this study:
The relative impact of genes and experience on development. Whether the development is best described as gradual and continuous or as a sequence of separate stages. Whether personality traits remain stable or change over the life span.6. When does the DNA in a cell replicate?
a. before cell division (mitosis or meiosis)
b. during cell division (mitosis or meiosis)
after cell division (mitosis or meiosis)
d. at random times throughout the cell's life cycle
Answer:
the answer is A before cell division (mitosis or meiosis)
Explanation:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.
List 4 major characteristics of this Sea Otters.
Answer:
The sea otters can close their nostrils and their auditory passages in the water.
The fifth toe of each leg is longer, which allows them to swim more easily, but hinders their movement on land.

Organisms can be classified in the same species by morphology and _____.
1. What is the relationship between an individual and a community?
2. What characteristics define a population?
3. Why is the distinction between a community and an ecosystem important to ecologists?
4. Define species.
5. What is an ecosystem?
6. Define population. How is a population different from a community?
Explanation:
1.) The relationship between an individual and a community is very close. Essentially, "society" is the regularities, customs, and ground rules of anti-human behaviour.2.) The number of people who live in a particular area, region, City, or country.4.) A group of plants and animals that are all the same and that can breed together.5.) All the plants and animals in a particular area consisted together with their surroundings.6.) A population is a group of organisms belonging to the same species that live in the same area and interact with one another. A communist is all of the population of different spices that live in the same area and interact with one another. A communist is composed of all of the biotic factors of the area.out of these three gases ( carbon dioxide, hydrogen gas, and methane) which could be a component of water

The overriding problem with both theories of muscle growth, hypertrophy and hyperplasia, is that __________. A. neither can be accepted as correct because muscles growth is difficult to study in humans B. neither one is theoretically possible C. neither has been studied by reputable scientists D. neither has been accepted by member of the fitness community Please select the best answer from the choices provided.
Answer: A. neither can be accepted as correct because muscles growth is difficult to study in humans.
Explanation:
Hypertrophy can be defined as the increase in the fiber size of the muscle whereas the hyperplasia can be defined as the increase in the number of muscle fibers. Additionally the hypertrophy suggests that adding more proteins to the fibers is suggestive of the growth of the muscles. But these two theories cannot be directly related to the muscle growth in humans as the development and growth of muscles are dependent upon several factors like diet, any kind of disease which restrict the muscle growth and movement, physical activities, mineral availability responsible for growth, malnutrition, and others.

Based on this information, which statement correctly describes the relationship between the two populations of tree frogs?
A.They are in the same species but different kingdoms.
B.They are in the same genus but different species.
C.They are in the same family but different orders.
D.They are in the same class but different phyla.
Which chemical equation is balanced to show that matter is conserved during the reaction? *
Answer: Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. Therefore, there must be the same number of atoms of each element on each side of a chemical equation.
Explanation:
The law of conservation of energy states that energy cannon be created or destroyed.
O True
O False
Answer:
false
Explanation:
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.

What is the function of Stomata?
Answer: Stomata, the small pores on the surfaces of leaves and stalks, regulate the flow of gases in and out of leaves and thus plants as a whole. Stomata are composed of a pair of specialized epidermal cells referred to as guard cells (Figure 3). Stomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore.

What are mushrooms? ಥ‿ಥ
mushrooms are funguses that need the dark to grow
mushrooms can be poisonous sometimes
Cells that live in environments where oxygen is present only a small amount of the time have two options to survive. They can be obligate anaerobes, which are poisoned by oxygen and do full cellular respiration with an electron transport chain that ends in a different molecule than oxygen (such as sulfur.) Alternatively, they can be facultative anaerobes that do full cellular respiration with oxygen when oxygen is available but do fermentation with glycolysis when oxygen is not available. Full cellular respiration makes 32 ATP per glucose. Glycolysis makes only 2 ATP per glucose. Write out which option you think is better in an environment that only occasionally (rarely) contains oxygen, obligate or facultative anaerobe, and defend your answer.
by defending the answer is that aerobic respiration is used by oxygen but anaerobic respiration is not used by oxygen also plants they do survive at night but human being cannot breathe the same air with plants at night because oxygen take place but at the daytime we use carbon dioxide this is how I do understand in my understanding
