<h2><u>Answer:</u></h2><h3><u>Question 1:</u></h3>
The correct option is A (a curved path)
Explanation:
Their way is diverted by the revolution of the earth. This is the Coriolis impact. This is the motivation behind why wind streams on the northern side (north half of the globe) turn counter-clockwise and that blows south of the equator, the southern side of the equator, turn clockwise.
<h3><u>Question 2:</u></h3>
The correct option is B (forms at or near the ground)
Explanation:
Fog is an obvious vaporized comprising of modest water beads or ice precious stones suspended noticeable all around at or close to the Earth's surface.
Haze can be viewed as a sort of low-lying cloud, more often than not taking after stratus, and is vigorously impacted by adjacent waterways, geology, and wind conditions.
Answer:
Although higher levels of testosterone in women cause an increase in muscle mass, this condition is also associated with health problems including, among others, infertility, polycystic ovarian syndrome, hirsutism, sleep apnea, irregular menstrual cycles and obesity, and therefore affecting their athletic performance.
Explanation:
A high level of testosterone in females not only influences their physical appearance, and its imbalance has been associated to health issues that affect women's athletic achievement. Testosterone is a hormone that controls gene expression in multiple organs and one of the most important metabolic regulators of sugar, lipids and proteins, thereby level higher than normal may cause the loss of the organism's homeostasis in women.
Answer:
C
Explanation:
I think its C . A transcriptional repressor usually represses the transcription pathway when its active. According to the question, the repressor is not usually active until an effector molecule binds to it making it active and blocking the transcription pathway. So if the region where the effector binds on the repressor is mutated i.e. it turns nonfunctional that means the effector cannot bind to repressor which means repressor cannot become active to block transcription which in turn increases the transcription of gene A because repressor cannot repress it since it is inactive due to its inability to bind to the effector.
ALOT of words please lmk if it makes sense
Answer:
a. Mammalia
Explanation:
Mammalia are the class species that have distinct systems and separate ducts for different activities like reproduction, excretory, and defecatory and moreover they have nipples to feed their young ones.
So, the above species which has a single duct for reproductive, excretory, and defecatory material as well as a lack of true nipples does not belong to Mammalia
