Answer:
The probability that they will have a daughter with the disease is zero, 0.
Note: Further information about the couple is given in the previous question shown below:
Tim and Stephanie are devastated when they find out their newborn son has hemophilia - a sex-linked recessive disease. Tim is shocked because he doesn't have hemophilia, and figures if his son has it he would have gotten it from him. Is Tim correct in his thinking? Explain. Also explain what their genotypes must be in order for neither of them to have the disease but have a son who does.
Explanation:
Hemophilia is a sex-linked recessive disease which results in the inability of the blood to clot normally. The abnormal gene for the inheritance of this disease is present in the X-chromosome. Males are not carriers of this disease as any male who have the abnormal X-chromosome will always have the disease but women can be carriers of the disease if the abnormal gene is only on one XX-chromosome.
From the information provided above, it can be determined that the genotype of Tim and his wife is XY and XhX, such that the wife is a carrier (Xh is the abnormal gene for hemophilia while X is the normal gene) and Tim is a normal male.
In the event that Tim and Stephanie now have a baby girl, the likely genotype of the baby girl can be obtained using the Punnett square shown in the attachment below.
The probability that they will have a daughter with the disease is zero, 0.

Name two actions
that you could take to reduce elephant poaching.
Answer:
increase protection and communal conservancies
Explanation:
increase protection this one is a fairly basic solution, there are many different ways of implementing it. Some park protection agencies in Africa use drones to keep watch at night, while others have sought out military tactics in order to stop black market poachers. Communal conservancies despite global trends, Namibia has done something extraordinary. Between the years of 2002 and 2013, the elephant population has grown from 9,600 to 16,000. The government of Namibia has policies in action where local communities can establish wildlife tourism, and where communities can keep vast amounts of the revenue made.

The somatic motor division consists of somatic motor neurons that innervate cardiac, smooth, and skeletal muscle cells. The somatic motor division consists of somatic motor neurons that innervate cardiac, smooth, and skeletal muscle cells. True False
Answer: FALSE
Explanation:
The nervous system is the system that detects and responds to changes inside and outside the body. This system consists of the brain, the spinal cord and peripheral nerves. The structure and organisation of the tissues that form these components enables rapid communication between different parts of the body.
Parts of the nervous system includes:
--> Central Nervous System ( consists of the brain and spinal cord)
--> Peripheral Nervous System ( consists of nerves outside the brain and spinal cord).The two functional parts of the peripheral nervous system are made up of the sensory (afferent) and motor (efferent). The motor division is involved in activities that are voluntary (somatic nervous system) and involuntary (autonomic nervous system).
The somatic motor division consists of somatic motor neurons that innervates ONLY the SKELETAL MUSCLE for its voluntary actions while the autonomic motor neurons innervates the cardiac and smooth muscles. Therefore the statement is FALSE

Answer:

Explanation:
Materials in cells may be transported by passive or active processes, both of which may involve concentration gradients, the phospholipid bilayer, and membrane proteins. Part A: Compare the role of concentration gradients in passive and active transport. Part B: Compare the role of the phospholipid bilayer in passive and active transport. Part C: Compare the role of membrane proteins in passive and active transport.
Answer:
Concentration gradients:
Passive transport: In favor ----> Simple Diffusion and facilitated diffusionActive transport: AgainstPhospholipid bilayer
Passive transport: Small particles or molecules can pass through the membrane----> Simple diffusionActive transport: Big particles or molecules need proteins to pass from one side to the other of the membraneMembrane proteins
Passive transport: Channel proteins in favor of electrochemical gradient---> Facilitated diffusionActive transport: Transporters or carrier proteins help molecules to pass to the other side of the membrane the electrochemical gradient.Explanation:
Diffusion: Refers to the pass of some small polar hydrophilic molecules through the lipidic bilayer. There are momentary membrane openings that allow small molecules to freely move from one side to the other in favor of the electrochemical gradient. These openings are the result of the lipids movements. The membrane permeability depends on the size of the molecule. The bigger the molecule is, the less capacity to cross the membrane it has. Diffusion is a very slow process, and to be efficient requires short distances and pronounced concentration gradients.
Facilitated diffusion: Occurs when big hydrophilic molecules cannot move freely across the membrane. In these situations, channel proteins are in charge of passive transport. Facilitated diffusion also occurs in favor of electrochemical gradients, meaning that molecules move from the more concentrated side to the less concentrated side.
Simple diffusion and facilitated diffusion are passive transport processes because the cell does not need any energy to make it happen.
Active transport is against the electrochemical gradient, so it does need energy to happen. Molecules move from a lower concentration side to a higher concentration side. This process is always in charge of carrier proteins. In primary active transport, the energy needed comes from the ATP molecule. In secondary active transport, the energy comes from the membrane electric potential.
Transmembrane proteins act in active and passive transport, connecting cells, and participating in signal transduction.
Channel proteins act by passive transport (these proteins do not need energy to carry in or out substances. They do it according to an electrochemical gradient) and carrier proteins act during active transport (these proteins do need the energy to transport substances because they do it against an electrochemical gradient). These transmembrane proteins carry in those substances needed by the cells to properly perform their activities, and they can also carry out waste substances.

Which part of the cell theory do these results most support:
[tex]\huge\textbf{Cell Theory}[/tex]
the Cell Theory was give by German scientists, Schleiden and T.Shwan in 1839. It stated that,
All organism are composed of one or more cellsThe cell is the structural and functional unit of life It is a de novo structure, that means it COULD arise from non living thing which was incorrect.It was corrected by the German pathologist Rudolf Virchow in 1855. He made a convincing case, corrected and added the third point of the cell theory. It is,
Cells can arise only by a division of pre-existing cell. It is NOT a de novo structure.Cell theory brought a great evolution in the field of biology which established the function of organism is the result of activities and interaction of the cell units.

Flask 1: It is observed that there are no micro-organism, this is because the meat is sealed and no micro-organism could enter through it.Flask 2: It is observed that there are micro-organism present because meat is not sealed but open.Flask 3: As the S tube is used, the micro-organism are not able to reach the meat because of the curvy pathThese observations support the point that cells could arise only by a division of pre-existing alive cells because in Flask 1 when there were no micro-organism present so there was no organisms found so no micro-organism arised, In flask 3 the S tube was used so no micro-organism could reach the meat thus there were no organism there which could divide to reproduce. The flask 2 was open, so the micro organisms reached the meat so they divided which means Cells can only arise by a division of pre-existing cells.
_____________________________________Best Regards,'Borz'All these experiments explain that cells only form from preexisting cells, as microbes give rise to the synthesis of new organisms, and this explains the cell theory through all these experiments.
What is cell theory?Cell theory is a fundamental concept in biology that describes the basic unit of life and its properties, and here in flask 1, if the meat is properly sealed and handled in a sterile environment, it is possible that no microorganisms could enter through it and explain that no growth is seen as no microbes are present. In flask 2, as the meat is open and exposed, it is more likely that microorganisms could be present and potentially grow. Microorganisms are ubiquitous in the environment and can be found in soil, water, air, and on surfaces such as countertops, utensils, and cutting boards. The use of an S tube could potentially reduce the amount of microorganisms that reach the meat due to the curvy path that is present in flask 3.
Hence, all these experiments explain that cells only form from preexisting cells, as microbes give rise to the synthesis of new organisms.

How do Rosa's body systems work together to get the molecules she needs into her cells?
Answer:
Digestive system and circulatory system.
Explanation:
Rosa's body systems such as digestive system and circulatory system etc work together to get the molecules she needs into her cells. the digestive system provides molecules needed by the cell from break down of food molecules in order to generate energy in the form of ATP while on the other hand, circulatory system is responsible for the transportation of molecules or substances from one part to another part of the body.
What is the function of ATP, and why is it important?
ATP(adenosine tri-phosphate) stores energy between it's 2nd and 3rd phosphate groups. When the 3rd phosphate group is released ADP(adenosine mono-phosphate) is created and energy is being released. This molecule is important because it stores the energy from cellular respiration and most cellular processes require the energy released by ATP.

light energy where you have it and Move glucose to where carbon dioxide is and Move carbon dioxide to where glucose.
What is photosynthesis?Plants absorb water and carbon dioxide from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell.
Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.
The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
Therefore, light energy where you have it and Move glucose to where carbon dioxide is and Move carbon dioxide to where glucose.
