Answer:
If twins are a boy and a girl, clearly they are fraternal twins, as they do not have the same DNA. A boy has XY chromosomes and a girl has XX chromosomes. Girl-boy twins occur when one X egg is fertilized with an X sperm, and a Y sperm fertilizes the other X egg.
Explanation:
If you move a plant further and further away from a light source the level of O2 production would _______________ because the process of _____________________ slows and the process of _____________________ speeds up.
Answer:
1. Decrease
2. Photosynthesis
3. Cellular respiration
Explanation:
Photosynthesis in a plant requires light source to occur. The photosynthetic process gives oxygen gas (O2) as a waste product. This means that the production of oxygen is dependent on the intensity of light.
On the other hand, cellular respiration uses up or consumes oxygen in a plant. Hence, an increase in respiration reduces oxygen level if photosynthesis does not produce.
According to this question, If you move a plant further and further away from a light source, the level of O2 production would DECREASE because the process of PHOTOSYNTHESIS slows and the process of CELLULAR RESPIRATION speeds up.

A tertiary consumer is an animal that obtains its nutrition by eating primary consumers and secondary consumers. Usually tertiary consumers are carnivorous predators, although they may also be omnivores, which are animals that feed on both meat and plant material. Function of Tertiary Consumers
Answer:
The function of tertiary consumers is to keep the population of primary and secondary consumers under control, in addition to serving as food for quarternary consumers.
Explanation:
As stated in the question above, tertiary consumers are those who feed on secondary and primary consumers within the food chain. They represent a very important trophic level, in addition to allowing the transfer of energy between living beings to flow normally, they manage to control the populations of primary and secondary consumers, which keep nature in balance. In addition, they serve as food for other consumers, the quarternarios consumers.

The tricyclic antidepressant drugs are monoamine agonists in that these drugs Group of answer choices block the reuptake of norepinephrine and serotonin into the terminals. stimulate the release of glycine within the limbic system. speed up the reuptake of norepinephrine and serotonin into the terminals. block NMDA receptors. block the reuptake of dopamine into the terminals.
Answer:
The correct answer is - block the reuptake of norepinephrine and serotonin into the terminals.
Explanation:
Tricyclic antidepressants drugs help in increasing the levels of hormones such as norepinephrine and serotonin, two neurotransmitters. The level of these hormones are increased by blocking the reuptake of these neurotansmitters and hormones back to axon terminal.
Reuptake of neurotansmitters and chemical messangers is the general mechanism of the balancing the horone levels in the body.

Read the passage “ a river for everyone”, then answer two questions below.( the entire passage is in the image above)
1. Are there any limits on what you can change? For example, it would not be realistic to
remove all of the farms. Is there anything that people cannot compromise on?
2. What else would you need to know to come up with a plan of action? Where could you
get that information?
Answer:
1. Moving the facilities such as crops, lawns, golf courses, and sewers etc would be unrealistic to change because many of the owners would not comprise (costs so much already), yet there are solutions. For example, the town can restrict farmers from poluting the rivers with pesticides as well as fining them and the house developments golf courses and land owners in which the money can be used towards the filteration cost. Another idea would to build cheaper wells to soak up water from different river locations or build barriers around settlements from the river. Another idea would to simply grow natural filters such as using the trees and soil they already had.
2. Of course their are limits such as costs, and figuring out the landscapes of where to build wells, add soil and trees (trees take time to grow) and more that would need plan of action from community leaders in which the people would need to speak with the advisors or the management of the buildings nearby. Without clean water people will get sick or die, and building managers need healthy people to live in their houses and work and grow crops so they'll have to make change.
A general mechanism by which postsynaptic potentials are terminated involves Group of answer choices increased synthesis of the neurotransmitter molecule. enzymatic synthesis of the neurotransmitter molecule. reuptake of the neurotransmitter molecule into the axon through a membrane transporter. increased number of postsynaptic receptors. diffusion into glial cells.
Answer:
The correct answer is - reuptake of the neurotransmitter molecule into the axon through a membrane transporter.
Explanation:
The action of a neurotransmitter at the postsynaptic cell or postsynaptic potentials is terminated by any of these mechanisms that are enzymatic degradation, diffusion or reuptake into the presynaptic cell by specific transporters.
After the desired biological response by postsynaptic potentials, in order to avoid over stimulation or termination of the postsynaptic potentials the neurotransmitter is taken back into the axon through a membrane transporter. This mechanism is to maintain a balance.
Tại sao chúng ta lại trụt rút
Answer:
Có rất nhiều lý do mà khóa tu là quan trọng! Chúng giúp chúng ta loại bỏ bản thân khỏi sự quen thuộc của những khuôn mẫu thông thường hoặc môi trường xung quanh, để dành thời gian để đến với Đức Chúa Trời trong sự Sáng tạo của Ngài. Thông thường ở những thời điểm khác nhau trong cuộc sống, một lý do hoặc nhu cầu này có thể vượt trội hơn lý do khác. Tuy nhiên, luôn có những lý do chính đáng, bất kể mùa nào trong đời của bạn, rằng một khóa tu là rất quan trọng để lên lịch, lập kế hoạch và tham dự. Dưới đây chỉ là bốn trong số chúng và chúng tôi nghĩ bạn có thể nghĩ ra nhiều hơn nữa!
Gần như hàng ngày, chúng tôi nhận được các cuộc gọi hoặc chuyến thăm từ những người đã đến Wafloy hơn 20, 30, 40 năm trước. Niềm vui khi trở thành một trung tâm nhập thất 72 tuổi là chúng tôi được nghe những người khác chia sẻ những kỷ niệm đó. Mối liên kết của những ký ức này không chỉ buộc họ với một nơi, mà còn với tình đồng nghiệp của những người khác đã đi cùng một hành trình. Chúng ta, con người, được tạo ra để giao tiếp với Chúa và với nhau. Dành thời gian như một nhóm, cô lập trong bầu không khí phát triển và dễ bị tổn thương có thể cho phép Đức Chúa Trời di chuyển trong cuộc sống. Điều này sẽ tạo ra những ký ức gắn kết vượt ra ngoài bản thân sự kiện khóa tu. Những ký ức đó và tác động của chúng có thể tồn tại suốt đời.
