When the CO₂ levels are higher on mars then the biomass of the plant will be increased and the nutritional value will be decreased.
Biomass is defined as the total quantity of any substance per unit area or volume. The biomass is made up of carbon element, hence more the carbon in any substance more is its biomass. Since the CO₂ are high in martian soil, this depicts high biomass of potatoes there.
Nutritional value is defined as the balanced proportion of all the components like carbohydrate, proteins, fats, etc. Since the CO₂ content is high it will lead to more amounts of carbohydrates then the proteins and other components.

The component part of the AEC the functions to measure the amount of radiation transmitted are known as detectors, cells, chambers or sensors, which suggests that all of the options are correct.
AEC is the acronym of Automatic Exposure Control, which includes ionization chambers which measures the exiting and striking photons from the patients body and the receptor screen. AEC device determines the exposure time. It consists of a density control panel which enables the radiologist to terminate the photon emission once a prescribed amount of photons are released into the body. AEC is widely used in radiographic and mammographic imaging systems. Detectors and sensors are included to sense the amount of photons emitted by the device.

What most likely would contribute to a global food shortage?
a. The Green Revolution
b. climate cooling
c. sea levels decreasing
d. a decrease in the amount of arable land
e. reductions in CO2 and methane levels
Correct option is D - a reduction in the amount of arable land
Any area that can be plowed and used to grow crops is considered arable land. Loss of arable land caused a global food crisis because it will be harder to produce the amount of food required to feed the world's expanding population as more arable land is lost.
Although there are many causes of hunger and food insecurity that differ from one country to the next, in general, these factors include conflict, poverty, economic shocks like hyperinflation and rising commodity prices, as well as environmental shocks like flooding or drought.
Arable land is land that is routinely worked (ploughed or tilled), usually through a system of crop rotation.

Thus, an animal with a theory of mind believes that mental states play a causal role in generating behavior and infers the presence of mental states in others by observing their appearance and behavior under various circumstances. But all people seem to frequently reason about mental states, except those who have a disease like autism. However, they do not identify mental states with behavior.

colchicine is a drug that blocks the assembly of microtubules. if dividing cells are treated with colchicine, at what stage of mitosis would you predict the arrest would occur?
The correct option is D : Prophase is the initial stage of mitosis, which is the process by which the duplicated genetic material carried in the nucleus of a parent cell is separated into two identical daughter cells.
During prophase, the nucleus's combination of DNA and proteins, known as chromatin, condenses.
Colchicine's inhibit the development of spindles during mitotic metaphase. As a result, it hinders chromosomal separation during the anaphase stage. Colchicine is a mitotic inhibitor, which means it suppresses the M phase.

What is sex chromosomes ?
A specific form of chromosome involved in determining sex is called a sex chromosome. The two sex chromosomes, X and Y, found in humans and the majority of other mammals, together define an individual's sex.
Male cells include one X and one Y chromosome, while female cells contain two X chromosomes. The sex of a person generated through sexual reproduction is determined by the human sex chromosomes, a typical pair of mammal allosomes. In a diploid cell, autosomes emerge in pairs with members that share the same form but differ from other pairs, whereas allosome pair members may differ from one another and hence affect sex.

The neurotransmitter released between two nerve cells binds to a ligand gated ion channel in the receptor cell.
An action potential is a rapid sequence of changes in the voltage across a membrane. When a neurotransmitter binds to the ligand gated ion channel, it triggers opening of the channel and causes inflow of sodium ions inside the neuron. This depolarizes the cell.

All primates are descended from creatures that lived in trees, they all possess characteristics that make them capable of climbing trees, such as a rotating shoulder joint, separated large toes and thumbs for grabbing, and stereoscopic vision.
Geneticists have proposed over the past 45 years that the ancestors of modern humans and chimpanzees parted between 4 and 6 million years ago, and the ancestors of gorillas between 7 and 9 million years ago. However, since chimpanzee and gorilla fossils are scarce, these dates were determined by measuring the number of DNA sequence variations between the three species and dividing that number by an assumed "mutation rate" for primates, or the rate at which mutations appear through time. The issue is that scientists frequently use dates from fossils of other monkey species to compute the mutation rate before applying this rate to African apes and humans.

Because allolactose stimulates the activation of the lac repressor when it is present, the lac operon is known as an inducible operon (see the symbol(s) available for a portion). The right response in this case is option B.
Because the lac operon typically turns off but can switch on in the presence of the inducer allolactose, it is referred to as an inducible operon.
An inducer, which is often a chemical, activates the repressor and initiates transcription (lac operon). An inducible operon called lac comprises genes that code for the lactose hydrolysis and metabolism-related enzymes.
