Effect of temperature on blood

Low temperatures cause narrowing of blood vessels and arteries which leads to restricting blood flow and reducing oxygen to the heart.

Our heart must pump harder to circulate blood through the blood vessels which results in increasing of our blood pressure and heart rate.

Answer:

Option 3.

totipotent stem cells → pluripotent stem cells → multipotent stem cells → neuron

Explanation:

The development of the various stages of stem cells in the embryonic stage is described here:Totipotent stem cells: Right after the mitosis of the zygote which results in the formation of two identical daughter cells, which are totipotent stem cells. Totipotent stem cells possess the ability to give rise to 220 different types of cells in the embryo including the placenta.Pluriopotent stem cells: These types of cells possess the ability to change into any type of cell in the body like blood, muscle, etc. It is formed at the embryonic stem cell stage.Multipotent stem cells: These stem cells have the ability to change into specialized cell such as forming different organs in the body. It occurs as the pluriopotent cell develops in the embryo.Neuron: As the multipotent cell has the ability to form a specialised cell it gives rise to the heart, lungs, liver, etc. including neurons.

transcription starts with ____ and makes ____ with the aid of ____________

Answers

1. Initiation
2. RNA molecule
3. Sorry do not know the correct answer

Answer:

transcription starts with Initiation/the nucleus/DNA and makes mRNA with the aid of Polymerase RNA enzyme

Explanation:

Transcription is the process in protein synthesis consisting of a starting process of initiation where the nucleus hosts the creation of an mRNA sending the coding message to the ribosome, but the starting process is the Polymerase binding to a site on the DNA strand, then it makes the mRNA through the other steps in transcription.

Which option(s) correctly describes chromosomes?
Chromosomes consist of tightly coiled DNA wrapped around proteins called histones
Each chromosome has one gene
Chromosome pairs contain completely different genes
Most human cells have two copies of each chromosome - one from each parent.

Answers

Answer:In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.

Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes.

What is the degree of the polynomial 3x^5-6x^2+5x?


A ) 8

B ) 7

C ) 2

D ) 5

Answers

Answer:

D.5

Explanation:

i took the test trust me

The degree of the polynomial 3x^5 - 6x^2 + 5x is 5, so the answer is option D.

A polynomial is a type of algebraic expression that consists of variables, coefficients, and exponents.

There can be one or more terms in a polynomial, and the degree of the polynomial is determined by the highest power of the variable present in it.

For example, the polynomial 3x^2 + 4x + 5 has a degree of 2 since the highest power of the variable (x) is 2. In the given polynomial 3x^5 - 6x^2 + 5x, the highest power of the variable is 5, which means that the degree of the polynomial is 5.

Hence, the correct answer is option D.

damage to the sinoatrial node in humans would ________.

Answers

Answer:

Explanation:

mark brainlliest

Damage to the sinoatrial node in humans can result in irregular heartbeats, abnormal heart rhythms, decreased cardiac output, and an increased risk of sudden cardiac arrest. Prompt medical evaluation and appropriate treatment are crucial to manage these effects and maintain a healthy heart rhythm.

Damage to the sinoatrial (SA) node in humans would result in disruptions to the normal electrical conduction system of the heart. The SA node is often referred to as the "natural pacemaker" of the heart because it initiates the electrical impulses that regulate the heartbeat. Here's how damage to the SA node would affect the heart:

1. Irregular Heartbeat: The SA node is responsible for setting the pace of the heartbeat. If it is damaged, the heart may beat too fast, too slow, or irregularly. This can lead to symptoms like palpitations, dizziness, and shortness of breath.

2. Abnormal Heart Rhythms: Without the SA node functioning properly, other areas of the heart may take over the role of generating electrical impulses. However, these impulses may not be coordinated or synchronized, resulting in abnormal heart rhythms such as atrial fibrillation or heart block.

3. Decreased Cardiac Output: The SA node helps regulate the timing of the heart's contractions, ensuring efficient blood flow throughout the body. Damage to the SA node can disrupt this coordination, leading to decreased cardiac output. This means that the heart may not be able to pump enough blood to meet the body's needs, resulting in symptoms like fatigue and weakness.

4. Risk of Sudden Cardiac Arrest: In severe cases, damage to the SA node can increase the risk of sudden cardiac arrest. Without the SA node's ability to regulate the heartbeat, the heart may stop pumping blood effectively, leading to a life-threatening emergency.

5. Treatment Options: Treatment for damage to the SA node depends on the severity and symptoms. In some cases, medication or cardiac devices like pacemakers may be used to regulate the heart's rhythm and ensure proper electrical conduction.

The ancestors of modern-day fish were vertebrate chordates. Vertebrate chordates are believed to have evolved from invertebrate chordates, which were similar to modern-day tunicates.

What change must have occurred during the evolution from invertebrate chordates to vertebrate chordates?

A.
A backbone evolved to enclose the notochord, which develops from the spinal cord.
B.
An endoskeleton evolved to enclose the spinal cord, which develops from the notochord.
C.
An endoskeleton evolved to enclose the dorsal nerve cord, which develops from the notochord.
D.
A backbone evolved to enclose the spinal cord, which develops from the dorsal nerve cord.

Answers

Answer:  

The correct answer is option B, that is, an endoskeleton evolved to enclose the dorsal nerve cord, which develops from the notochord.

Explanation:

It has been discovered that the ancestors of the modern-day fish were vertebrate chordates. The vertebrate chordates are considered to have evolved from the invertebrate chordates that are identical to the present day tunicates. It has been found that in vertebrates the endoskeleton has evolved to encompass the dorsal nerve cord that has been developed from the notochord (a characteristic of invertebrates).

C. An endoskeleton evolved to enclose the dorsal nerve cord, which develops from the notochord.

Organisms require a variety of chemical nutrients, such as NITROGENOUS, which are components of proteins, nucleic acids, and ATP. It is an essential element for life.

Nucleic acids, either DNA or RNA, contain nitrogen in the nitrogen bases of their nucleotides (i.e., Adenine, Guanine, Cytosine and Thymine, Uracil).

Adenosine triphosphate (ATP), the energy coin of the cell, contains nitrogen in its Thymine nitrogen base.

Finally, proteins are made of amino acids, whose building blocks are carbon, hydrogen, oxygen and nitrogen atoms.

what is the function of circuit breakers and fuses?​

Answers

Answer:

Fuses and Circuit Breakers both serve the same purpose – which is to protect electrical circuits by preventing overloads that can cause fires. They both interrupt the flow of electricity, but in very different ways from each other. While a fuse is made of a piece of metal that melts when overheated, circuit breakers on the other hand, have internal switch mechanisms that can be tripped by an unsafe surge of electricity.

Fuses can be quicker for interrupting the flow of power, but when they melt they must be replaced; circuit breakers on the other hand just need to be reset. When comparing the two, we’ll take a look at some of the major advantages and disadvantages between fuses and circuit breakers to distinguish between them.
