Answer:
Their are only two possibilities either the WW or Ww combination could occur.
Explanation:
As the man is homozygous for the trait thus it would produce the type of gametes which are all samiler means having the trait of only dominant charecter the gametes will be all samiler having the genotype of W. Women have different genotype with gametes of W and w so when during zygote formation the W combine with w so the zygote have genetic make up of Ww if the gamete having W genotype combine with W so the genetype would be WW.
The complex mixture of polymers coating the spore that protects the spore from dessication and UV radiation is:
Answer:
Sporopollenin
Explanation:
Sporopollenin is a biological polymer that is highly cross linked and made up of oxygen, hydrogen and carbon. It is referred to a chemically inert biopolymer because of its toughness and stability in rocks that have been in existence for over 500 million years. In other words, sporopollenin is chemically stable.
It is an important component of the outer layer or coating of pollen grains and plant spores. This protects spores from UV radiation and dessication.
Mammals like caribou that live in the arctic often have different lipids in the cells of their legs compared to the cells of their internal organs. Their legs get colder than their internal organs, which stay warmer. Indicate true or false which of the following adaptations you would expect to find in the lipids found in the cells of the legs of a caribou?
A. The lipids would be more saturated.
B. The fatty acyl tails of the phospholipids would be shorter.
C. The membranes would contain more cholesterol
Answer:
Mitochondria is the powerhouse of a cell
Explanation:
Oxytocin causes contractions during pregnancy, it also is the reason why mothers feel "motherly" towards their children after childbirth as there are high levels on oxytocin in the mother's blood.
The cells of caribou legs are not likely to have more saturated lipids, as it could impede their function in chillier temperatures. However, they may have shorter fatty acyl tails for more flexibility, and more cholesterol to fluidize the membrane.
Explanation:In polar environments such as the arctic, animals such as the caribou have adapted to the cold temperatures. One of these adaptations pertains to their cellular lipids.
A. It would be false to expect the lipids to be more saturated. Saturated lipids are packed tightly and are more rigid, which can solidify at chillier temperatures and impede cell function.
B. True, the fatty acyl tails of the phospholipids would more likely be shorter. Shorter fatty acyl tails have fewer interactions with each other, which allows for more flexibility in cold temperatures.
C. True, you would expect the membranes to contain more cholesterol. Cholesterol functions to fluidize the membrane and prevent it from becoming too stiff in low temperatures.

What is the function of photosystem ii?
Answer/Explanation:
Photosystem II is the first complex involved in the light-dependent reactions in photosynthesis.It is named photosystem II because it was the first photosystem to be discovered. Photosystem II is a huge complex of proteins (sometimes called a supercomplex) found in the thylakoid membrane of chloroplasts. Photosystem II captures energy from photons of light (from the sun) to oxidise two molecules of water to form molecular oxygen. This releases electrons and hydrogen ions.When light is absorbed by one of the many pigments (chlorophyll), energy is passed from pigment to pigment until it reaches the reaction center. There, energy is transferred to a special pair of core chlorophyll pigment molecules, called P680, raising an electron to a high energy state. The high energy electron is passed to an acceptor molecule and replaced with an electron from water. This splitting of water forms oxygenElectrons travel down an electron transport chain, driving ATP production and arriving at photosystem I, which is where more energy and ATP are produced to fuel the rest of the photosynthesis reactionsPhotosystem II captures light energy and converts it into chemical energy in the form of ATP and NADPH.
Explanation:The function of Photosystem II is to capture light energy and convert it into chemical energy in the form of ATP and NADPH, which are used in the process of photosynthesis. It is the first step in the light-dependent reactions of photosynthesis, taking place in the thylakoid membrane of chloroplasts.
The photosystem II complex consists of several protein and pigment molecules, including chlorophyll, that work together to absorb light and transfer the energy to the reaction center.

What is the term used for the phase when the cell divides
Final answer:
The phase when the cell divides is called the mitotic phase, which is part of the cell cycle and includes the processes of mitosis and cytokinesis resulting in the formation of two daughter cells.
Explanation:
The term used for the phase when the cell divides is the mitotic phase. This phase is a multistep process that includes both mitosis and cytokinesis. Mitosis is the part of the cell cycle where the duplicated chromosomes are aligned, separated, and moved to opposite poles of the cell, enabling nuclear division. Subsequently, cytokinesis completes the cell division process by physically separating the cytoplasmic components into two distinct daughter cells, each with an identical set of chromosomes.
The cell cycle consists of two general phases: interphase and the mitotic phase. Interphase is the period during which the cell grows, repairs itself, and replicates its DNA, preparing for mitosis. Interphase accounts for the majority of the cell's life cycle.

Which statement BEST explains how RNA polymerase knows where to start and stop making an RNA copy of DNA?
A. The enzyme binds to a sequence of nucleotides called introns that are cut out before they become functional.
B. The enzyme proofreads each DNA strand to help ensure each molecule is copied exactly in the order of the original strand.
C. The enzyme splices exons together before transcription begins to form the final mRNA molecule.
D. The enzyme only binds to regions of DNA known as promoters, which have specific base sequences.
"The enzyme only binds to regions of DNA known as promoters, which have specific base sequences" statement BEST explains how RNA polymerase knows where to start and stop making an RNA copy of DNA.
Option: D
Explanation:
Transcription is the mechanism which happens when polymerase of RNA (principal enzyme for transcription) attaches by aid proteins or personally or to a promoter segment near the gene beginning.
For generating a new molecule of RNA which is complementary, RNA polymerase utilizes one of the DNA strands or the parent strand as a template.
For an instance, trying to block mushroom toxicity transcription triggers liver failure and death, as no new RNAs and therefore no fresh proteins can be produced.
Final answer:
RNA polymerase starts transcribing at a region called the promoter and stops at a sequence known as the terminator. It recognizes these specific DNA sequences to transcribe the necessary genetic information into RNA, including coding exons and non-coding introns, which are spliced out to form the final mRNA.
Explanation:
The knowledge of how RNA polymerase begins and concludes the process of transcribing DNA into RNA is essential for understanding genetic expression. The correct answer to the question provided by the student is D: The enzyme only binds to regions of DNA known as promoters, which have specific base sequences.
The process initiates at the transcription start site within the promoter, a specific DNA sequence that RNA polymerase and associated proteins recognize and bind to, signaling the start of RNA synthesis. As transcription continues, the enzyme moves along the DNA, creating an RNA copy that includes exons and introns. However, before the resulting pre-mRNA is functional, non-coding introns are removed, and only the coding exons are spliced together to form the final mRNA molecule, which is then translated into a protein.
Finally, RNA polymerase reaches a terminator sequence, signaling the end of the gene and prompting the enzyme to release the newly formed RNA molecule and detach from the DNA.

You are analyzing the transmembrane proteins in cells from a developing mouse embryo and find that there are many integrins in the membrane and also in the cytoplasm. How would you explain their presence in the cytoplasm, given what you know about the roles of integrins
Explanation:
integrins are recycled through the cytoplasm after serving to transport developing cells in the embryo Integrins are the major and best-described trans-film receptors that intercede dynamic communications between the extracellular framework and the actin cytoskeleton during cell motility. Integrins are αβ heterodimers with a huge extracellular area that ties the extracellular framework (ECM) and connections to the actin cytoskeleton through a short cytoplasmic tail Restricting explicitness is dictated by the extracellular area of integrins that perceive different network ligands including fibronectin (e.g., α5β1, αvβ3, α4β1), collagen (e.g., α1β1, α2β1), and laminin (e.g., α2β1, α3β1, α6β1). Cell surface receptors including the Ig superfamily individuals ICAM-1 (αLβ2, αMβ2) or VCAM-1 (α4β1) are likewise perceived by integrinsAll in all, integrins tie to explicit themes inside the lattice protein; for instance, nine diverse integrins can tie to fibronectin and acknowledgment is generally through the focal cell- binding domain (Arg-Gly-Asp [RGD] theme)Shontae was diagnosed with PTSD following her return from a tour in Afghanistan.

Voice can reveal things about the speaker and the message. ________ is a listener's perception of how high or low a sound is, ________ is the basic tone that an individual uses most of the time, and ________ is the pitch movement within an utterance.
Pitch; habitual pitch; intonation.
Explanation:
A sound is the form of energy which produces the sensation of hearing in organisms.
A sound is judged on three properties:
Amplitude, that defines loudnessFrequency, that defines the pitch Quality or timbre.Pitch is the rate of vibration of the sound source. As the frequency of sound increases ,the pitch also increases and as the frequency decreases pitch also falls.
Normal pitch of voice that is generally used by a person while usual speaking is called his habitual pitch.
The change in pitch while speaking is called intonation, it gives an impressive tonal quality to the speech.
'Pitch' refers to the highness or lowness of a sound, 'vocal signature' is an individual's usual tone of voice, and 'intonation' is the variation in pitch throughout an utterance.
Voice can reveal things about the speaker and the message. Pitch is a listener's perception of how high or low a sound is, vocal signature is the basic tone that an individual uses most of the time, and intonation is the pitch movement within an utterance. These elements of vocalics play a crucial role in communication, adding nuance and expression beyond the mere words spoken.
Pitch refers to the frequency range of your voice, affecting how your voice is perceived in terms of highness or lowness. A vocal signature is your unique tone of voice, which can be recognized and often associates with your identity. Lastly, intonation involves the variation in pitch during speech, which can convey different meanings or emotions.

What theoretical perspective views society as having a system of interdependent inherently connected parts?
Answer:
Functionalism
Explanation:
Functionalism is the theoretical perspective in sociology, posits that for stability and social order to be established in a society, all social institutions that make up the society, must work interdependently to contribute to the functionality of the society. Social institutions in a society include, the government, family, economy, religion, media,education.
For example, for most societies that seem relatively stable, the family pay taxes to the government, the government as an institution rely on these taxes to provide education for the children of the family in that society. All parts of this society are interdependently inherently connected.
The theoretical perspective that views society as an interconnected system of interdependent parts is known as Functionalism or the Structural-Functional theory. Originating from the writings of Herbert Spencer, this perspective likens society to a human body, with every part serving a purpose and contributing to the overall function and stability of society.
Explanation:The theoretical perspective that views society as a system of interdependent, inherently connected parts is called Functionalism or the Structural-Functional theory. This perspective emerged from the writings of Herbert Spencer, an English philosopher and biologist, who likened society to the human body - just as the various organs of the body function collaboratively to keep it running, so too do the different parts of society, such as government, education, family, religion, and economy, work together to keep the society operating smoothly.
Central to this outlook is the understanding of society as something greater than just the sum of its constituent parts. A core tenet of Functionalism is that each part of society, no matter how seemingly insignificant, serves a purpose and contributes towards societal stability and continuity. For instance, a functionalist might investigate why global inequality exists, positing that it serves certain social purposes, or explore how social change in one area of a society (like the shift towards cocoa farming in Ghana) can irrevocably impact other areas (like gender relations).

According to the _____ theory, when a physiological need, such as hunger, creates an aroused tension state, it drives the organism to reduce the need.
Answer:
the drive-reduction theory
Explanation:
The drive-reduction theory is one of the theories of motivation.
This theory contains the idea that a physiological need creates a drive, which in turn motivates an organism to satisy their need.
The theory targets homeostasis or biological balance.
When there is a need such as lack of water, the need would cause a drive to be developed (thirst).
The drive would activate a response (search for water to drink).
The response is then terminated when the need has been satisfied.
According to the drive theory of motivation, physiological needs lead to psychological drive states that motivate behaviors to restore homeostasis, with such behaviors potentially becoming habitual.
Explanation:According to the drive theory of motivation, when an individual experiences a physiological need such as hunger, it creates a tension state that acts as a drive which in turn motivates the organism to engage in behaviors to reduce the need. This process is aimed at restoring the body's homeostasis. For example, when you are hungry, your blood sugar levels drop, leading to the physiological need to eat. This need then creates a hunger drive that motivates you to seek food, thus eliminating the hunger and bringing your blood sugar levels back to normal. The drive theory also emphasizes that once a behavior has successfully reduced a drive, that behavior becomes a habit which the organism is more likely to perform in the future when faced with the same drive.
