The hormone that controls the re absorption of sodium ions is Aldosterone
Explanation:
- Aldosterone is a steroidal hormone which stimulates and plays a role in the process of absorption of kidneys to regulate the salt and water balance
- When there is a reduction in blood flow to the kidneys due to the enzyme Renin it automatically activates the aldosterone process
- reabsorption of sodium is a part of renal function and it is restored by the angiotensien
- Aldosterone plays an major role in water and the salt reabsorption into the blood via the kidney

What would be the effect of a high external temperature on amount of urine produced by the kidneys
Answers
Answer:
Amount of urine produced by the kidneys is dependent on the external temperature of the environment. In summer season, the temperature of the surrounding is warm and more water is lost in sweating so the body produces less urine because body requires water for other functions of the body. In winter season, the temperature of the surrounding environment is cold so urine is produced in high amount.

If Earth were not tilted on its axis, what change would we experience? A)Day length would be less than 24 hours.
B)Both sides of the moon would be visible.
C)Temperatures would be constant year round.
D)The length of the year would be more than 365
Answers
Answer:
If Earth was not titled on its axis, Temperatures would remain constant year round, Option C.
Explanation:
Earth is tiled at 23.5 degrees. If it was not titled, there would no seasons, which means temperatures would not have changed around the year.
Earth has season because the axis on which it rotates is tilted at 23.5 degrees. The seasons occur as the tilted Earth travels in a loop around the Sun each year. When it is tilted 'towards' the sun, summer occurs in that hemisphere tilted. Winter season arrives when it gets tilted 'away' from the sun. This way different parts of Earth receive direct rays from sun. This is the reason days are longer during the summer as compared to during winters.

What is the difference between scientific argument and a regular argument?
Answers
Answer:In this paper, we argue that there is an emergent confusion in the literature in the use of the terms “argument'' and “explanation.” Drawing on a range of publications, we point to instances where these terms are either used inappropriately or conflated. We argue that the distinction between these two constructs is, however, important as a lack of clarity of fundamental concepts is problematic for a field. First, a lack of common conception hinders effective communication and, second, it makes defining the nature of the activity we might expect students to engage in more difficult. Drawing on a body of scholarship on argument and explanation, this paper is an attempt to clarify the distinction and to explain why such a distinction might matter.
Explanation:
Answer:
A scientific argument is when it had more examples of that certain argument. What I’m saying is that scientific arguments have more details and more evidence to why that answer is wrong or right. Regular arguments is when it is less detailed and just making predictions and theoretical analysis.

Which of these Earth spheres interacts with coral reefs to cause coral bleaching? Atmosphere Cryosphere Geosphere Hydrosphere
Answers
Answer:
The correct option is D) Hydrosphere
Explanation:
The corals present int he hydrosphere interact with the algae through a endosymbiotic relationship. This endosymbiotic relationship helps to maintain the health of the corals and the reefs. However, at a certain time, the coral reefs might expel the algae living inside it. This phenomenon is termed as coral bleaching. The corals generally expel the algae when they are under stress situations such as changes in temperature or availability of nutrients.

Answers
The sexual reproduction helps in having more variation among the offsprings. It also makes the offsprings more resistant to genetic diseases.
Explanation:
Sexual reproduction is the process by which the gametes of the species fused together to form zygote which develops into an offspring. This offspring produced has the gene from both the parents . This genetic setup is not only copied from the parents but they undergo the crossing over and independent assortment which leads to variation among the offspring itself as well as they differ from their parents too.
This variation among the offspring as well as the crossing over helps to eleminate the lethal genes from the genetic pool. Thereby they help to get more resistance among the offsprings from diseases.
Sexually reproducing species have the ability to produce genetically variation in the offspring.
Explanation:
- Sexual reproduction comprises two parents and the joining of male and female organisms when fertilization takes place.
- The offspring acquires a mixture of genes from both progenitors, so they are distinct from each other and their parents.
- In asexual reproduction, only one progenitor plays the role of producing the offspring which is identical to it.
- The newly formed offspring from sexual reproduction possess the characteristics of both the parents but in asexual reproduction, the offspring possess the characteristic of one parent only.
- In sexual reproduction, both male and female exchange their DND genetic material, as a result, a wider variety of gene combinations can be found in the resulting offspring.

Answers
Answer:
D
Explanation:
The gradient in bed load is mostly made up mostly of gravels and sands, broken down versions of larger boulders and rocks, which are most commonly found in mountainous areas. Streams with low gradients cannot carry bed load down stream because it moves slowly and without much force. Gravels and sands couldn't move downstream because the water flow isn't strong enough to move them or to keep them in motion.
