In emerging adulthood, physical development is generally considered to be complete, as individuals have typically reached their maximum physical height and strength.
The development of the brain is one aspect of physical growth that is crucial for emerging maturity. It may take until the mid-20s or later for the prefrontal cortex, which controls activities like decision-making, planning, and impulse control, to reach complete maturity.
Since people are normally healthy and have more time on their hands to participate in sports and other physical activities, emerging adulthood is also a time of increased physical activity and exploration.
However, some people may start to experience physical health losses at this time as a result of things like poor nutrition, inactivity, and elevated stress.

what would be the most direct effect on the cell if crispr were used to inactivate the genes that encode dna repair proteins?
When CRISPR is used to inactivate the genes that encode DNA repair proteins, the most direct effect on the cell would be that the cell will be more susceptible to DNA damage.
What is CRISPR?CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a DNA sequence found in bacteria and archaea that acts as an immune system against invading viruses or plasmids. The CRISPR sequence consists of identical repeat sequences separated by "spacer" DNA sequences, which is a DNA sequence of a previously encountered virus or plasmid.
CRISPR-Cas9, also known as the CRISPR-Cas system, is a revolutionary gene-editing technology. It works by utilizing RNA molecules and enzymes to make precise cuts in DNA to insert, modify, or delete specific genes. The CRISPR-Cas system is used in many biological fields, including medicine, agriculture, and basic science research.
How does CRISPR affect the cell?CRISPR-Cas9's most direct effect on a cell is that it causes DNA damage. The Cas9 enzyme cuts the DNA at the location specified by the guide RNA, inducing a double-stranded break (DSB) in the DNA. The CRISPR system then sends in repair mechanisms to fix the damage.
The double-strand breaks that CRISPR-Cas9 generates can have a significant effect on the cell, resulting in DNA damage, genomic instability, or the generation of a nonfunctional protein. Cells can also show off-target activity, where CRISPR-Cas9 cuts the DNA at unintended sites.

which extracellular signal proteins trigger a wave of g1/s-cdk activity? choose one: a. growth factors b. death receptors c. death factors d. survival factors e. mitogens
The extracellular signal proteins that trigger a wave of G1/S-CDK activity are called mitogens. The correct answer is option e.
Mitogens are extracellular signal proteins that stimulate mitosis or cell division. They activate the G1/S-cyclin-dependent kinase (CDK) complex, which is required for the initiation of DNA replication and entry into the S phase of the cell cycle.
Mitogens include growth factors, which promote cell growth and division, and other factors such as hormones and cytokines. When a mitogen binds to a cell surface receptor, it triggers a signaling cascade that ultimately leads to the activation of G1/S-CDK, allowing the cell to progress through the cell cycle.
Mitogens play a critical role in normal tissue growth and development and are also involved in various disease states, including cancer.
So, the correct answer is option e. mitogens.

Which idea did Lamarck propose that was rejected by his fellow scientists?
can i have brainest? please? anways hope i helped
Answer:
The correct answer will be acquired traits can be passed to offspring.
Explanation:
Lamarck is known for his idea of "inheritance of acquired traits" by studying neck size of giraffes and stated that:
1. New organs or traits can be produced by long use during lifetime as response to external environment,
2. characteristic is inherited to the next or succeeding generations.
3. Organ can disappear if not used.
Scientists were not able to find and explain evidence for the theory for example :
1. The blacksmith’s arm- enlarges when used continuously against external resistance like weight of the hammer but it is not necessary that the smith’s children at birth would have large arms or later in his life.
2. Skilled Hands of a musician- skillful hands of a musician causes no increase in the size of the fingers and this trait might be passed to musician’s children and they also play instrument skillfully with no practice.
Thus, acquired traits can be passed to offspring is the correct answer.

The reason(s) why glucose oxidation occurs in multiple, enzyme catalyzed steps that result in small chemical transformations is/are
The reason why glucose oxidation occurs in multiple, enzyme-catalyzed steps that result in small chemical transformations is to efficiently harness the energy stored in glucose molecules.
Breaking down glucose in small steps allows the energy released from each step to be captured and stored in molecules like ATP, which can then be used by cells for various metabolic processes. Additionally, breaking down glucose in small steps also helps to prevent a large, uncontrolled release of energy that could be damaging to the cell.
Enzymes are used to catalyze each step of glucose oxidation, allowing for precise control over the process and ensuring that each step occurs at the appropriate rate. Overall, this highly regulated process of glucose oxidation enables cells to efficiently convert the energy stored in glucose into a form that can be used for cellular activities.
The process of glucose oxidation occurs in multiple, enzyme-catalyzed steps that result in small chemical transformations because it allows for greater control and efficiency of energy release. Glucose is a complex molecule, and the breakdown of its chemical bonds releases a significant amount of energy that can be used by the cell.
However, releasing all of that energy at once would be inefficient and potentially harmful to the cell.
By breaking down glucose into smaller, more manageable pieces through a series of controlled steps, the cell can harness the energy released in a controlled manner and use it to power various cellular processes.
The use of enzymes also allows for the regulation of these steps, ensuring that they occur only when needed and at the appropriate rate.
In addition, the multiple steps of glucose oxidation allow for the production of ATP, the primary energy currency of the cell, in a more efficient manner.
ATP production is coupled with the release of energy from the breakdown of glucose, so breaking down glucose into smaller pieces allows for more ATP to be produced for each molecule of glucose oxidized.
Overall, the multiple, enzyme-catalyzed steps of glucose oxidation are necessary for the efficient release and utilization of the energy stored in glucose, while also providing tight regulation and control over the process.

A scientist has discovered a new plant species in the Amazon rainforest she tells her fellow scientist at the Playhouse she has found for Tuesday is a cone for my side about this plan is different from an organism
Answer:
It is a seeded vascular plant.
It does not depend on insect pollination.
Explanation:
The complete question is: A scientist has discovered a new plant species in the Amazon rainforest. She tells her fellow scientists that the plant she has found produces a cone. What might they say about how this plant is different from an angiosperm? Its seeds have one or two cotyledons. Its stems' vascular bundles are scattered. It does not depend on insect pollination. It is a seeded vascular plant.
The correct option would be that the plant is a seeded vascular plant and does not depend on insect pollination.
Gymnosperms are the only group of plants that produce cones. They are one of the plant groups that have vascular tissues in the form of xylem and phloem as well as been able to produce seed in the form fo cones. Hence, they are said to be seeded vascular plants.
Gymnosperms also carry out their pollination by relying solely on wind for the transfer of their pollen grain to the female organ. In other words, they do not depend on insect for pollination.
Selective distortion could be described as perceiving stimuli (an event) in a way that makes you feel comfortable cognitively. True False QUESTION 3 Most of our thoughts happen at a conscious level. True False QUESTION 4 Perception and reality are distinct constructs, and not necessarily the same. True False QUESTION 5 100 calorie mini Oreos snack packs, and a regular box of mini Oreos are most likely not porceived the same way by consumers. True Falso
The given statement "Selective distortion could be described as perceiving stimuli (an event) in a way that makes you feel comfortable cognitively" is False.
Selective distortion refers to the process by which we perceive stimuli in a way that is consistent with our existing beliefs, attitudes, and expectations. This means that we may filter out information that contradicts our preconceptions, or interpret information in a way that reinforces them. This can lead to cognitive dissonance, which is the discomfort or anxiety that we feel when our beliefs and actions are inconsistent with each other.
False. Selective distortion can occur at both conscious and unconscious levels. At the conscious level, we may be aware of the ways in which we are filtering information, and we may be able to consciously control our perceptions to some extent. At the unconscious level, our perceptions may be influenced by our deep-seated beliefs and attitudes, which we may not even be aware of.
Most of our thoughts occur at a conscious level, but there are also many thoughts and perceptions that occur at an unconscious level. These unconscious thoughts and perceptions can be influenced by a wide range of factors, including our past experiences, our cultural background, and our current emotional state.
True. Perception and reality are not necessarily the same thing. Perception refers to the way that we perceive and interpret information through our senses. Reality refers to the objective state of things as they actually exist, independent of our perceptions. However, our perceptions can influence our understanding of reality, and our perceptions may not always be accurate or complete.
Perception and reality can be distinct constructs, but they are also closely related. Our perceptions can be influenced by our expectations, our past experiences, and our cultural background, among other factors. At the same time, our perceptions can also provide us with information about the world around us that is independent of our subjective experiences.

If fertilization is considered day 0, when do cells lose totipotency in human development?.
Human development begins with the fusion of an ovum and sperm to form a zygote during fertilization. This zygote is totipotent, as it has the ability to become any cell type within the human body.
A zygote, a eukaryotic cell, is created after the fertilization of two gametes. All of an individual organism's genetic material is included in the genome of a zygote, which is made up of the DNA from each gamete. In multicellular organisms, the zygote is the first stage of development. A sperm and an oocyte combine to form this cell. A zygote is where a new human being is created. The term "fertilized ovum" describes a secondary oocyte that has been successfully fertilized by a sperm, resulting in the development of a zygote. The earliest stage of conception, commonly referred to as fertilization, is the zygote stage. It's likely that you won't be able to tell if fertilization has taken place at this point.
