why is mechanical digestion of food important?? please help I only need one reason marking brainliest btw
Answer:
it makes the food smaller
Explanation:
Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.

why it is important to base scientific theories and models on empirical evidence as opposed to other ways of knowing such as religion
Answer:
A theory not only explains known facts; it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable. New evidence should be compatible with a theory.

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.

what are the consequences of either an incomplete or absent ""s"" stage of the cell cycle?
Answer:
If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.
Explanation:
The consequences of an incomplete/absent "S" stage in a cell cycle are ;
A programmed cell death The cell will not move to the G2 phase of the cell cycleThe absence or incomplete "s" stage of the cell cycle occurs when the a cell does not completely copy its chromosomes or when there is a significant damage to the genetic material ( DNA ) of the cell. when any of these abnormalities occurs the "s" phase stage of the cell cycle will not be activated until the cell chromosomes are correctly copied. Therefore the cell will not move to the G2 phase of the cell cycle
Hence we can conclude that The consequences of an incomplete/absent "S" stage in a cell cycle are ; A programmed cell death and The cell will not move to the G2 phase of the cell cycle

If laco were mutated, what effect would this have on lactose metabolism?
Answer:
If lacO were mutated, what effect would this have on lactose metabolism? The repressor would not properly bind to the operator, and the lac operon would be over expressed. How does the cell recognize that lactose needs to be metabolized? Lactose is converted into allolactose, which inhibits the lac repressor.
