what are the types of tropism
Answer:
Forms of tropism include phototropism (response to light), geotropism (response to gravity), chemotropism (response to particular substances), hydrotropism (response to water), thigmotropism (response to mechanical stimulation), traumatotropism (response to wound lesion), and galvanotropism, or electrotropism (response to electric current).
Tropism is a response to certain stimuli. A positive tropism is moving towards the stimuli, while a negative tropism is moving away from a stimuli.
Positive Phototropism - Growing towards light
Negative Phototropism - Growing away from light
Positive Thigmotropism- Moving towards touch
Negative Thigmotropism- Moving away from touch
Positive Hydrotropism - Growing towards water
Negative Hydrotropism - Growing away from water
Positive Gravitropism - Growing towards ground
Negative Gravitropism - Growing upwards

Explanation:
Use the drop-down menus to complete the hypothesis of the first group of researchers. During a drought, the decrease in rainfall will reduce the amount of vegetation that can grow and increase the occurrence of natural fires, so an elevation in Select… and a reduction in Select… should be found in the cores.
Answer:
Microscopic charcoal, Vegetation.
Explanation:
As the researchers conducting research in the Nile region identified that an increase in temperatures leads to an increase in droughts and reduction of natural vegetation and thereby the chances of the occurrence of natural fires.You farm kelp and sell the kelp for food and as fertilizer. The wastes from the kelp can be used in an integrated aquaculture system in which kelp farming can be coupled with farming of fish or abalone. Make an argument that you are using a sustainable system of growing a renewable resource, and explain why it is beneficial (and more sustainable) to couple algae farming with fish farming than simply to farm fish independently.
Answer:
A sustainable system refers to producing less or probably non-existent debris that are caused by the production of a particular material (i.e. produce, energy). This is a sustainable form of production of coupling algae growth and fish farming because you no longer need the supply of fish feed from other sources that are made artificially but rather, you are using the available algae growth that you are culturing. Farm fishing alone is non-renewable because this produces much waste that can directly harm the environment.
An integrated aquaculture system of fish farming with kelp farming is a sustainable system as both system exchange resources and thus reduce wastage of resources.
What is an integrated aquaculture system?An integrated aquaculture system is an aquaculture system which combines several forms of aquaculture together.
For example, kelp farming is a form of aquaculture which can be integrated with another form of aquaculture such as fish farming.
Integrating fish farming with kelp farming is a sustainable system as both system provides what the other needs.
The kelps serve as food to fish while fish waste serve as manure for kelps.
Therefore, integrating fish farming and kelp farming is a form of a sustainable system.

Ca and phosphate reabsorption decreases 5. Ca reabsorption decreases and phosphate reabsorption increases 6. Ca reabsorption increases and phosphate reabsorption decreases
Answer:
2. Parathyroid hormone level decreases
4. Ca and phosphate reabsorption decreases
Explanation:
When plasma Ca concentration decreases, the action of Parathyroid hormone level decreases which leads to Calcium and phosphate reabsorption decreases. Parathyroid hormone is responsible for the increase of calcium and phosphorus in the blood when there is low level in the blood so when the re is huge amount of calcium and phosphorus in the blood, the Parathyroid hormone activity decreases which decrease the reabsorption of calcium and phosphorus decreases.

We have all heard about earthquakes or the cyclones that attack the coastal regions. Think of as many different ways as possible in which people's health would be affected by such a disaster if it took place in our neighbourhood. (a) How many of these health -related events would occur long after the actual disaster, but would still be because of the disaster? (b) How can it affect the life of people if in case of a pandemic?
Answer:
The disease spread to the neighbourhood.
Explanation:
If the disaster such as earthquake and pandemic etc occurs in the neighbourhood so it also affected the health of the people of that region as well as the people that lives in the neighbourhood. In the case of pandemic, the disease spread to the neighboring area and affect the health of people while on the other hand, in earthquake the people of neighbourhood is also affected if the intensity of earthquake is higher.

Answer:
is a thick band of neural fibers enabling communication between the two brain hemispheres.
Explanation:
A brain can be defined as an organ of soft nerve tissue that is found in the skull of vertebrates and it's typically responsible for the coordination of nervous activities, intellect and sensation.
The human brain consists of various sections and these includes;
I. Anterior Cingulate Cortex (ACC) which resembles a bow or collar surrounding the frontal part of the corpus callosum. This is the frontal part of the cingulate cortex which helps to make complex cognitive functions such as impulse control, decision-making, emotions and empathy.
II. Ventral prefrontal cortex in humans are interconnected with the brain and are responsible for the processing of risk, empathy, fear and social decision-making
III. The Cerebral Cortex: this part of the brain primarily comprises of grey matter, foldable sheets of neurons and forms its outermost layer. Therefore, cerebral cortex is known as the outermost layer of the brain (cerebrum) and thus, makes up half of its weight. It is about 2.5 millimeters in thickness and as such it's able to fold.
The corpus callosum is a large, thick band of C-shaped neural fibers found beneath the cerebral cortex and it's saddled with the responsibility of enabling communication between the two brain hemispheres i.e the right hemisphere and the left hemisphere.

Here, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.
What is Punnett Square?The Punnett square is a tool used to predict the probability of offspring inheriting specific alleles from their parents. If all of the offspring exhibit the same phenotype (such as purple flower color), it is likely that the parents both carried at least one dominant allele for that trait. This would mean that the purple flower color allele is dominant. Here, the parents are both purple and white, so all the offspring are dominant in nature.
Hence, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

what type of transport takes place when a protien allows an ion to enter a cell, but no additional energy is needed to make this happen?
Answer:
The answer is facilitated diffusion. It requires no energy because the ions are traveling down the concentration gradient. Facilitated diffusion is important for the regulation of ions in a cell. It also enables ions to pass across the hydrophobic layer of the cell membrane composed of phospholipids.
An antibody molecule has a molecular weight of 150 kD when analyzed by SDS polyacrylamide-gel electrophoresis (SDS-PAGE). Treatment with mercaptoethanol, a reducing agent that breaks disulfide linkages, yields polypeptides with molecular weights of 50 kD and 25 kD, and both of these bands are similar in intensity and thickness. Based on this gel pattern as described, what can we conclude about the molecular composition of the antibody molecule
Answer:
The antibody has a molecular weight of 150 kD and consists of four subunits: two subunits of 50 kD and two subunits of 25 kD, which are bonded by covalent bonds.
Explanation:
Sodium dodecyl sulfate (SDS) is a detergent used to alter and denature proteins before gel electrophoresis. SDS can break hydrophobic interactions and hydrogen (H) bonds, but this detergent does not break down disulfide bonds, which is a type of covalent bond between two sulfur atoms. Moreover, mercaptoethanol is a reducing agent used to break disulfide bonds. In this case, it is expected that mercaptoethanol can break disulfide bonds between the four subunits of the mature antibody, thereby yielding two bands corresponding to the 50 kD and 25 kD bands (two subunits of 50 kD + two subunits of 25 kD = 150 kD).
