Explanation:
a movement away from the midline of the body is termed
Answer:
A movement of a body part away from the midline, either of the body as a whole or that of the hand or foot, is termed abduction (L., to carry away). A movement of the body part back toward the midline (i.e., to the anatomical position) is known as adduction.
Explanation:
Mark me brainly please.
Abduction is a movement away from the body's midline. Abduction is the term for a bodily part's lateral movement away from the body's midline.
Thus, body parts are divided or spread apart in this process. Abduction of the arms, for instance, occurs when you raise your arms from a resting posture and spread them out to the sides. Similar to this, you are practicing leg abduction when you stretch your legs apart.
Adduction, or the movement in the direction of the midline, is the reverse of this action. Important terminology like abduction and adduction are used to describe movement in respect to the body's midline in anatomical and physiological descriptions.

what is located in the autonomic nervous system
Answer:
It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.
Explanation:
The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS) contain both afferent and efferent fibers that provide sensory input and motor output, respectively, to the central nervous system (CNS). Generally, the SNS and PNS motor pathways consist of a two-neuron series: a preganglionic neuron with a cell body in the CNS and a postganglionic neuron with a cell body in the periphery that innervates target tissues. The enteric nervous system (ENS) is an extensive, web-like structure that is capable of function independently of the remainder of the nervous system. It contains over 100 million neurons of over 15 morphologies, greater than the sum of all other peripheral ganglia, and is chiefly responsible for the regulation of digestive processes.

During exercise, the blood is travelling more quickly around the body. This carries more oxygen to the exercise muscles. Describe other changes in the athlete's body that enable more oxygen to be taken in at the lungs.
Answer:
your heart rate goes up explaining why the blood is traveling quicker. this causes you to breath faster meaning bring more oxygen to the blood in your lungs faster. your blood pressure also goes up from the increase in heart rate.
Answer:
the breathing rate and volume of each breath increases to bring more oxygen into the body
Explanation:
it removes the carbon dioxide produced. the heart rate increases, to supply the muscles with extra oxygen and remove the carbon dioxide produced.

what type of ions carry the impulse across the synapse from one neuron to the next ?
It's the sodium ion.
When a neural impulse is fired in both neurons, it is always cause by an excited electron in one neuron moving to the other neuron to destabilize the balance of ions trying to keep them at equilibrium. This action either depolarizes or hyper-polarizes the membrane. If it does, then sodium ions--the key deficient ones--can flow into that region of low charge and maintain that state of low charge, keeping the cell membrane stable.

2. Body cells undergo the process of mitosis while gametes undergo a process called meiosis.
3. A body cell contains a complete number of chromosomes and is called a diploid cell while a gamete contains only half the number of chromosomes of its parent cell, and it is called a haploid cell.
3. Identical twins
4. nucleotide triplets
5. A gene is a sequence of nucleotide bases that specifies certain products; RNA or proteins. It is the segment of DNA that holds the information to build and maintain an organism's cell and also pass genetic traits to offspring. Hence, it is the molecular unit of heredity in living organisms.
The DNA is a long double-helical structure that stores the genetic information in our cells. It consists of two long polynucleotide chains composed of the four nucleotides subunits (A, C, G, T).
In order for the long strand of DNA to fit into the cell's nucleus, it is coiled around certain proteins called HISTONES to form Chromatin, which undergoes further coiling and organization to to linear CHROMOSOMES.
The chromosomes are structured within the nucleus, that are made up of the cell's genetic material (DNA). In eukaryotic cells, the nucleus houses the cell's DNA and directs protein synthesis (expression of the information encoded by genes).

lon khoáng nào đóng vai trò đặc biệt quan trọng trong quá trình đông máu?
Answer:
1. Xét nghiệm yếu tố đông máu để làm gì?
Để đánh giá khả năng đông máu như thế nào và quá trình đông máu kéo dài trong thời gian bao lâu, các bác sĩ sẽ tiến hành xét nghiệm các yếu tố đông máu.
Quá trình đông máu sẽ bảo vệ cơ thể bạn khi bị chảy máu. Tuy nhiên, nếu một cục máu đông hình thành trong tĩnh mạch bình thường thì đây là điều hết sức nguy hiểm vì có thể khiến cho dòng máu bị chặn đến tim, não, phổi.
Khi thực hiện xét nghiệm các yếu tố đông máu, sẽ biết được nguy cơ bạn bị chảy máu quá nhiều khi bị thương hay không hoặc có nguy cơ bị đột quỵ không.

2. Các yếu tố đông máu gồm những gì?
Fibrinogen
Fibrinogen là yếu tố ảnh hưởng lớn đến quá trình đông máu
Sau đây là các yếu tố ảnh hưởng đến quá trình đông máu:
I - Fibrinogen: Fibrinogen là huyết tương có trọng lượng phân tử là 340.000, hòa tan được. Yếu tố này có mặt trong huyết tương với nồng độ là từ 100-700mg/ 100mL. Đa số Fibrinogen được tạo ra ở gan, vì thế đối với những bệnh nhân bị bệnh gan thì lượng Fibrinogen giảm trong máu tuần hoàn, sự đông máu bị ngăn cản.
II- Prothrombin: Prothrombin là protein huyết tương có trọng lượng phân tử là 68.700, có mặt trong huyết tương với nồng độ là 15mg/100mL. Gan sản xuất Prothrombin liên tục, chính vì vậy nếu gan bị suy yếu, lượng prothrombin sẽ giảm, gây ức chế sự đông máu.
III- Thromboplastin mô: Yếu tố này tham gia vào cơ chế đông máu ngoại sinh, thay thế phospholipid tiểu cầu và các yếu tố huyết tương. Bên cạnh đó, thromboplastin còn có tác dụng chống nhiễm khuẩn.
IV- Ca++: Quá trình đông máu không thể không có mặt của loại ion này.
V- Proaccelerin: Khi có nhiều ion Ca++ thì yếu tố này mất hoạt tính. Khi không có proaccelerin, người ta điều chế huyết tương bằng cách để lâu huyết tương lấy từ máu chống đông với oxalat.
VII- Proconvertin: Trọng lượng phân tử của yếu tố này là 60.000. Hoạt tính của yếu tố này trong huyết tương sẽ bị giữ lại trên màng lọc amiang;
VIII- Antihemophilic A: Để tổng hợp yếu tố này, phụ thuộc vào rất nhiều gen trong các nhiễm sắc thể khác nhau. Thường thì antihemophilic được tổng hợp chủ yếu từ gan, lá lách và hệ thống võng nội mô. Khi thiếu ion Ca++ thì yếu tố này mất hoạt tính. Đây là yếu tố chống huyết hữu B;
IX- Antihemophilic B: Chống huyết hữu A.
X- Stuart: Stuart có trong huyết tương, ở dưới dạng không hoạt động. Trong quá trình đông máu nội sinh có sự tham gia của yếu tố này. Khi cho thromboplastin mô vào quá trình đông máu ngoại sinh, sẽ không còn yếu tố stuart.
XI- Plasma Thromboplastin Antecedent (PTA): Quá trình khởi phát đông máu nội sinh không thể thiếu yếu tố PTA.
XII- Hageman: Động lực để tạo thành một loạt phản ứng dẫn đến đông máu là sự tiếp xúc giữa yếu tố XII với mặt trong mạch máu tổn thương cùng sự có mặt của phospholipid tiểu cầu. Bên cạnh chức năng hoạt hóa hệ đông máu, Hageman còn hoạt hóa hệ đông máu, hệ bổ thể và hệ chống đông.
XIII - Fibrin Stabilizing Factor ( FSF): yếu tố này có hoạt tính bền vững trong huyết tương, ổn định fibrin.
Explanation:
In an experiment that compares a combination mental-physical practice condition to an all-mental practice condition, an all-physical practice condition, and a no practice condition, the typical results show that participants in the combination mental-physical practice condition would learn the skill
a. as well as or better than those in the all-physical practice condition.
b. about as well as those in the all-mental practice condition.
c. about as well as those in the no practice condition.
d. The results would depend on the combination of the amount of mental and physical practice.
The combination mental-physical practice condition is effective to learn the skill as well as or better than those in the all-physical practice condition. Mental-physical practice enhances both cognitive and physical skills.
Mental practice, also known as mental/skill rehearsal, refers to the cognitive (i.e., thinking) rehearsal of a given skill prior to its execution.
It has been shown that mental practice can be effective for enhancing the performance of both cognitive and physical skills.
The mental-physical practice has been shown to be helpful to enhance self-motivation, confidence, and reduce feelings of anxiety.
Mental practices always must be employed to supplement physical practices instead of replacing such physical exercises.
