What can bacteria do with “broken down” materials ?

Answers

Answer 1
Bacteria have the ability to break down dead organisms into smaller particles and create new compounds. We use decomposers to restore the natural nutrient cycle through controlled composting. Bacteria secreting enzymes out of their cells into the soil or dead organism. The enzymes digest the organic material. When they break down organic material, they give off heat. Billions of aerobic bacteria working to decompose the organic matter in a compost pile causes the pile to warm up. As the temperature rises, different organisms thrive.

1. Two plant species grow together in an oak savanna. One is fairly long-lived and produces few large seeds. The other is short-lived and produces many small seeds. a. What are the ecological advantages and disadvantages of each

Answers

Answer:

d

took the test

Explanation:

Large seeds advantages:

They have a higher chance of germination and thriving.

Large seeds disadvantages:

They can not easily spread to new areas.

Small seed advantages:

They can spread easier to new areas.

Small Seed disadvantages:

They have a lower chance of surviving.

Large and small seeds main difference resides in their structure. The structure allows them to survive or to cover new areas. The disadvantage is that it can only do one of the two things.

Large seeds, as they are larger:

They have a structure that allows them to store more energy than small seeds. As a consequence, they have more elements to thrive and grow into a plant than small ones.Due to their size, they are heavier. They do not spread as far as the others.

Small seeds :

They do not have enough energy to grow, so they need more aid from the environment than large ones. In other words, their chances of survival are lower.The advantage is that they can colonize wide areas due to their lightness. So, even though they are small, they spread easier and cover more territory than large seeds.

To sum up, small seeds have a lower chance of survival, but they are more and cover longer distances. While large ones have a higher chance of survival, but they are fewer and cover short distances.

35 °C and 45 °C C
35 °C and 55 °C D
45 °C and 55°C

Answers

Answer:D

Explanation:

The optimum temperature for the enzyme is between 45 °C and 55°C. Therefore, option (D) is correct.

What is an optimum temperature for enzyme?

Most enzymes perform best at a temperature of around 98.6 degrees Fahrenheit (37 degrees Celsius). Additionally, some enzymes function well both at low and high temperatures. For instance, while animals in desert climates have enzymes adapted to higher temperatures, those in the Arctic have them adapted to lower optimal temperatures.

The reaction rate will accelerate as more hydrogen peroxide is added to the mixture because more substrate molecules can interact with the enzyme and produce more product as a result. As you increase the amount of H2O2 in your reaction, more foam is generated in your cup as a result.

compared to parasympathetic ganglia, sympathetic ganglia are __________.

Answers

Compared to parasympathetic ganglia, sympathetic ganglia are autonomic ganglia of the sympathetic nervous system that prepare the body for emergency situations, such as: defense or flight reactions to a dangerous situation.

In the parasympathetic ganglia, the axons of neurons are characterized by being very long and reach the very structure of the target organ before making contact with the second neuron.

On the other hand, these ganglia activate the parasympathetic system that has to do with energy recovery situations such as: activating digestive secretions, reducing blood flow to the brain, which causes drowsiness.

In the sympathetic ganglia, axons originate from neurons located in the lateral horns of the spinal cord and exit through the anterior roots of the spinal nerves, along with those of the motor neurons.

These ganglia activate the sympathetic system that prepares the body for dangerous situations causing: increased heart rate, blood pressure, respiratory rate, etc.

Therefore, we can conclude that compared to parasympathetic ganglia, sympathetic ganglia are autonomic ganglia of the sympathetic nervous system that prepare the body for emergency situations.

Answers

Answer:

it contains iron that gives it the red color when exposed to oxygen

Human blood-red and not blue because Hemoglobin contains iron that gives the blood the red color when exposed to oxygen. The correct option is c.

What is hemoglobin?

Hemoglobin is a red color pigment that is present in the blood. It contains a heme group that carries oxygen into the body and carries carbon dioxide outside the blood. It is red and in some animals, it is blue because of copper.

Hemoglobin is made up of four protein chains that each bind an additional ring-shaped chemical structure called heme. Our red blood cells are red because of the heme groups in hemoglobin. In turn, our blood is red because of the millions of red blood cells that it contains.

Therefore, the correct option is c. Hemoglobin contains iron that gives the blood a red color when exposed to oxygen.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.

Moreover, photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.

Hence, the primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process. It's not particularly efficient by human engineering standards, but it does the job.

lon khoáng nào đóng vai trò đặc biệt quan trọng trong quá trình đông máu?

Answers

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.
