The bullhorn acacia trees have a mutualistic relationship with the acacia ants, where the ants protect the trees and in return, the trees provide shelter and food for the ants.
Bullhorn acacia trees have a mutualistic relationship with acacia ants. The ants protect the trees from herbivores and other plants that may compete for resources. In return, the trees provide shelter and food for the ants.
The bullhorn acacia tree has specialized structures called Beltian bodies, which are rich in nutrients. These structures are produced by the tree and are specifically meant to be consumed by the ants. The ants also benefit by feeding off nectar produced by the tree's extrafloral nectaries.
Overall, the ants receive food and shelter, while the tree benefits from protection against herbivores and the ability to outcompete nearby plants.

Answer:
The plants provide food and accommodation in the form of food bodies and nectar as well as hollow thorns which can be used as nests. The ants return this favor by protecting the plants against herbivores
Explanation:
In order to increase the rate of photosynthesis in a plant, a plant should be developed with many broad leaves. The broad leaves will have increased surface area and more chlorophyll. The increased number of the leaves in the plant will also contribute to the overall increased rate of the photosynthesis.
A strong and thick stalk will support the plant but will have no effect on the rate of photosynthesis. Narrow leaves will decrease the photosynthesis rate. Bright flowers will aid in pollination via the honeybees but not increase the photosynthesis rate.
Hence, the correct answer is 'many broad leaves'.
The correct option is D.
A virus refers to an infectious micro organism that is made up of nucleic acid molecule that is enclosed within a protein coat. Viruses are only able to reproduce and multiply when they come in contact with living cells, in the absence of living cells they remain dormant and they do not show any sign of been a living thing. The nuclei acid molecule of a virus can be in form of a DNA molecule or a RNA molecule.
Answer: The answer is D/RNA or DNA core surrounded by a protein coat.
Explanation: One reason a virus is considered to be a particle rather than a cell is because structurally it is only a RNA or DNA core surrounded by a protein coat. It has none of the other features of bacterial cells.
A. reduced water or food intake
B. infectious organisms
C. elevated or depressed blood pH
D. extreme temperatures.
Homeostasis, the body's ability to maintain internal balance, can be challenged by reduced food or water intake, infectious organisms, changes in blood pH, and extreme temperatures. These challenges can disrupt the body's normal functions and cause varying health impacts.
The body's ability to maintain a relatively constant internal environment, called homeostasis, can indeed be challenged by various factors. Reduced water or food intake can alter the balance of nutrients and hydration in the body, potentially leading to dehydration or malnutrition. Similarly, infectious organisms such as bacteria, viruses, or parasites can disrupt homeostasis by causing disease.
Elevated or depressed blood pH, which refers to the acidity or alkalinity of the blood, can disrupt bodily functions if it falls outside of a certain range. Finally, extreme temperatures can challenge body's ability to regulate its own temperature, potentially leading to conditions like hypothermia or heat stroke.

Answer:
A single nucleotide polymorphism (SNP) is the most common gene variation found among people. A SNP represents a change in a single DNA block, called a nuecleotide, being able, for example, to replace a nucleotide cytosine (C), with a nucleotide thymine (T), guanine (G) or adenine (A) in the genome. They represent the 90% of all the human gene variations.
Explanation:
5 feet
0.2 feet
2.5 feet
Answer:
Option (A)
Explanation:
Here, the given question is based on the scale-model.
a height of 10,000 feet on the actual mountain range is taken equivalent to 1 foot in the model .
so we can write it as,
10,000 feet=1 feet
1 feet=(1÷ 10,000) feet
Therefore,
5000 feet={(1÷ 10,000)×5,000} feet
5000 feet=0.5 feet
So, we can determine that a height 5000 feet on the actual mountain range is equivalent to a height of 0.5 feet on the model.
Hence, the smallest mountain on the model is 0.5 feet.
