Answer:
If plants could grow at any angle, resources could be better used, less labor would be spent, and crop production would increase.
Explanation:
By growing at different angles, crops could be generated in different locations that would not normally be beneficial or feasible for plant growth.
For this reason, land use would be higher for farmers as harvests would increase by making better use of the land and generating ideas to make better use of resources.
They could be better used, for example, a scale cultivation on a sloping terrain, no time would have to be spent flattening the ground and only the crops would have to be cared for.
How will the movement of substances be altered in the phloem during spring season? Why?
Answer:
The phloem is responsible for transporting food from leaves to other parts of the plant.
The transport of pholem is bidirectional and changes the movement of particles according to the season. Generally, the transportation occurs in the direction of the source to sink but in spring season the direction is opposite that is from sink to source because the source and sink are n opposite sides. So in spring season, the stem tubers are sources and the growing leaves are sinks.

Answer:
d. adrenals; ACTH
Explanation:
The steroid hormones cortisol and corticosterone are released by the adrenals in response to the hormone ACTH( Adrenocorticotropic hormone).
High levels of ACTH send signals to the adrenal gland receptors which stimulate the secretion of cortisol. The cortisol is helpful in controlling blood sugar levels, regulating metabolism and helping to reduce inflammation
Conalan wants to answer the quesionn does phosphrus affect tomato fruit production? Which statement represents a hypothesis that he can test to answer his question
Answer:
If phosphorus affects tomato fruit production, then plants that are fertilized with phosphorus will produce more tomatoes.
Explanation:
The available options to the question are:
If phosphorus affects tomato fruit production, then tomatoes that are fertilized with phosphorus will have larger leaves.
If phosphorus affects tomato fruit production, then phosphorus should be added to the soil during planting.
If phosphorus affects tomato fruit production, then adding phosphorus to the soil will make tomatoes taste better.
If phosphorus affects tomato fruit production, then plants that are fertilized with phosphorus will produce more tomatoes.
The correct answer here would be that "If phosphorus affects tomato fruit production, then plants that are fertilized with phosphorus will produce more tomatoes."
The hypothesis represents a tentative statement relevant to the research being carried out. What researchers do during the course of researching is to test the validity of hypotheses with experiments.
Since the main aim of the research is to find out if phosphorus affects tomato fruit production, the relevant hypothesis must effectively address the main aim of the research.
The production of tomato can only be measured from the yield of tomato fruits produced by the tomato plants. If phosphorus does indeed affect tomato fruit production, then the tomato plants that are supplied with the element will produce a higher yield of tomato fruit as compared to the ones without phosphorus.
Which of these can be decomposed by a chemical change?
Answer:
B) CO
Explanation:
Chemical decompsition or breakdown is defined as the process in which a substance can be broken down into simpler compounds through chemical means.
CO or carbon monoxide can be decomposed by chemical change because it can be broken down into into carbon and oxygen.

Help!! Which of these are amphibians and which are reptiles? Tree frog Alligator Crocodile Salamander Newt Common lizard
Answer:
tree frogs → amphibians
alligator → reptile
crocodile → reptile
salamander → amphibians
newt → amphibian
common lizard → reptiles
(✿◠‿◠) hope this helps...
Answer: Hi!
These animals are reptiles:
Alligator
Crocodile
Common Lizard
Reptiles are cold - blooded animals. Their class includes snakes, lizards, crocodiles, turtles, and tortoises. They usually have dry, scaly skin, and typically lay soft-shelled eggs on land. Reptiles need to bask in the heat to keep their body temperature up. If their surroundings are cold, then their internal temperature drops.
These animals are amphibians:
Tree Frog
Salamander
Newt
Amphibians are cold blooded animals as well! They are small creatures that need water, or a moist environment, to survive. Most amphibians start off their life cycle in the water, and then transform into an animal with lungs and legs! Cool, right? The most known for this process are frogs and toads.
Hope this helps!

Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
3.Explain how energy from the sun can eventually be used for active transport in the alimentary canal
(7 marks)
Answer:
See the answer below
Explanation:
First of all, the radiation energy from the sun is converted to chemical energy by green plants in a process known as photosynthesis. The equation of the process is represented below:
[tex]6CO_2 + 6H_20 + (radiation) -->C_6H_1_2O_6 + 6O_2[/tex]
The chemical energy is locked up as carbohydrate in the green plants. When humans or any other animal consumes green plants or any of their products, the carbohydrate is broken down through a process known as respiration. The equation of the process is as below:
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + energy[/tex]
The locked-up energy - usually in the form of ATP - becomes available to be used for various metabolic processes in the body, including active transport in the alimentary canal.
In some cases, humans or animals generally do not consume green plants directly. They consume organisms that consume green plants. Such humans are still able to extract some of the energy through respiration and use it for their metabolic processes.
