In a flock of sheep there are animals with brown fleece and brown eyes and others with white fleece and blue eyes. There are no animals with white fleece and brown eyes or with brown fleece and blue eyes. What can you conclude about the genes for fleece color and eye color
Answer:
In general, children inherit their eye color from their parents, a combination of the eye colors of Mom and Dad. A baby's eye color is determined by the parents' eye color and whether the parents' genes are dominant genes or recessive genes.
A lamb inherits 2 genes for color, one from each parent. This color gene causes the pigment named eumelanin to be produced in the cells of the wool follicles. This pigment produces the basic black or brown color of the Icelandic sheep.

Through a microscope, you can see a cell plate beginning to develop across the middle of a cell and nuclei forming on either side of the cell plate. This cell is most likely Group of answer choices
Answer:
the cell is most likely a plant cell in cytokinesis
Explanation:
Cytokinesis simply means the division of the cytoplasm. It happens after the telophase stage of the cell division and leads to the formation of two distinct cells.
Cytokinesis in animal cells involves the constriction of the plasma membrane from the equator of the cell outward until two distinct cells result. The process starts from the anaphase and continues through the telophase stage of the cell division.
Due to the presence of cell walls in plant cells, cytokinesis does not just involve the constriction of the plasma membrane but the formation of cell plates at the equator of the cell. The cell plate fuses with the plasma membrane, eventually dividing the cell into two with the formation of cell walls between the two membranes of the cell plate.
The cell is most likely a plant cell undergoing cytokinesis.
CYTOKINESIS:
Cytokinesis is the process whereby the cytoplasm divides into two halves. Cytokinesis proceeds nuclear or mitotic division. Cytokinesis occurs in both plant and animal cells with similar result, however, they occur differently. In plant cells, a cell plate forms in between the cell, which serves as the point of division into two cells. However, in animal cells, a cleavage furrow is rather formed. Therefore, the cell observed to be forming cell plate is most likely a plant cell undergoing cytokinesis.Learn more: https://brainly.com/question/10606931?referrer=searchResults

Answer: 1. How can a healthy lifestyle lead to a healthy heart.
The heart is one of the vital if not the most vital organ of the human body,this is because it is the heart that pumps blood into systemic circulation so that the other body organs,tissues and cells can function adequately.
Any disease or injury to the heart virtually affects all other parts of the body. Therefore a healthy and proper functioning heart is important and this can only be achieved through a healthy lifestyle.
Lifestyles such as;
- Regular exercise/physical activity which will help one to loose excess weight and maintain physical fitness because when one is overweight,fat deposits on the wall of the artery narrowing the lumen/wall, this in-turn causes blood to exert more pressure as it moves through the artery and in-turn lead to hypertension and other heart conditions.
- Stop or limit the intake of alcohol because it increases your chances of getting stroke,heart attack and hypertension through the damage of heart muscles.
- Drinking enough water; this helps the kidney to filter away waste from the body preventing the waste from building up/accumulating in the body especially the heart and as such causing heart problems.
Managing of stress very well to prevent a higher risk of heart disease.
-Eat a healthy diet and manage your blood cholesterol level to prevent damage to heart muscles and blood vessels which will in-turn lead to cardiovascular disease.(High density cholesterol HDL is the good type of cholesterol and low density cholesterol (LDC) is bad for the body.
- Regular visit to a cardiologist when one has a family history of hypertension or any other heart disease.
2. HOW IS HYPERTENSION A BLOOD RELATED DISEASE?
Hypertension is a blood related disease because hypertension is caused when the force of blood along the lumen of artery (artery wall) is higher than normal. This exerted pressure by the blood gets too intense enough to cause a heart problem or a hear disease.
When the pressure gets too intense enough to rupture the artery wall,the individual comes with a heart condition known as stroke.

The ulnar artery goes medially deep to the pronator teres muscle and it moves along the different parts of the forearm and hand with the ulnar nerve.
Thus, the correct answer is - radial and ulnar
Drag each tile to the correct box. Arrange the steps in the correct order to describe how a reflex occurs. A receptor detects a signal. A sensory neuron sends a signal to the spinal cord. A bone moves. A relay neuron sends a signal to a motor neuron. A muscle receives a signal to contract. ↓ ↓ ↓ ↓
The reflex arc is the sequence of events since a stimulus reaches the body, until the body reacts to it. The correct order is a, b, d, e, c.
What is the reflex arc?The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts to it.
In general terms,
A stimulus of varying nature reaches the body. The peripheric nervous system -PNS- receives the stimulus and sends this information to the central nervous system -CNS-. The CNS processes the information and sends another signal as a response to the stimulus.This mechanism is known as the reflex arc.
Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.
There are three types of neurons involved in the mechanism:
• Afferent or sensorial neurons
• Interneurons
• Efferent or motor neurons
Action:
Ascending branch1) The stimulus reaches the body and is received by the specialized sensory receptors.
2) Information is received by these receptors and converted from stimuli energy (temperature, pressure, light, etc.) to action potential energy.
3) Afferent neurons, placed in the dermis and epidermis, receive information from receptors, react and send the information to the central nervous system as nerve impulses.
Descending branch4) Once the information reaches the central nervous system, it is processed by the interneurons that analyze it before sending a response.
5) Interneurons manage many sensorial signals, evaluate and compare them, and send a motor response.
6) Efferent neurons receive information from the interneurons and are stimulated to carry these new signals from the central nervous system to the cells of the effector organs. The effector organ can be a muscle or a gland.
7) Finally, the target tissue responds to the stimulus as a contraction, if it is a muscle, or as hormones release if it is a gland.
In the exposed example, the corrcet order is
a- A receptor detects a signal.
b- A sensory neuron sends a signal to the spinal cord.
d- A relay neuron sends a signal to a motor neuron.
e- A muscle receives a signal to contract.
c- A bone moves.

Answer:
Sympathetic nervous system makes the body ready to fight or fight response during any danger in the body.
While
Parasympathetic nervous system slow the body from performing too much work there by restoring the body to calm and composed state
Explanation:
The autonomic nervous system is divided into two; the sympathetic and parasympathetic nervous system. The autonomic nervous system controls the involuntary actions of internal organs and glands.
The sympathetic nervous system originate from the spinal cord and and it's is responsible for accelerateing the heart rate, constricting blood vessels, and raising blood pressure. Thereby preparing the body to fight or fight response against any danger.
The parasympathetic nervous is a part of autonomic nervous system that also originate from the spinal cord which which slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. By doing this,it prevent the body from overworking itself and restore the body to a calm and composed state.

Which one of the following statements about lysosomes is incorrect? If one of the many types of acid hydrolases found in the lysosome is nonfunctional, a lysosomal storage disease can develop. Lysosomes are acidic because they contain acid hydrolases. Lysosomes release the monomeric building blocks (like amino acids and nucleotides) into the cell. Autophagosomes form in the cytosol around old or broken down organelles; later, the autophagic vesicle fuses with a lysosome. Resident lysosomal proteins display a mannose-6-phosphate group which targets them to a late endosome.
Answer:
B. Lysosomes are acidic because they contain acid hydrolases.
Explanation:
Lysosomes are small cell organelles that float outside nucleus. Lysosomes are present in the cytosol of the cells.
Lysosomes are acidic in nature having pH below 5 because of proton pumping through the plasma membrane to maintain this acidic pH.
This acidic nature of lysosomes play a role in fight against diseases.
Hence, the correct option is "B".
