Answer:
Apples : adenine
Trees : thymine
Cars : cytosine
Garages : guanine
Explanation:
The bases in DNA are adenine, thymine, guanine, and cytosine. It helps to remember the popular mnemonic, "apples in the tree," that helps you remember that A goes with T, and "car in the garage," so C goes with G, to understand how DNA bases pair. The bases in RNA are adenine, uracil, guanine, and cytosine.

Name some harmful substances found in cigarette smoke. How do these
substances affect the respiratory and the circulatory systems?
Answers
Nicotine
Formaldehyde
Lead
Arsenic
Ammonia
Radioactive elements such as Polonium-210
Benzene
How some of those chemicals affect the body:
Nicotine is highly addictive and can cause an increase in blood pressure, heart rate, flow of blood to the heart and a narrowing of the arteries (vessels that carry blood).
Symptoms for formaldehyde are watery eyes; burning sensations in the eyes, nose, and throat; coughing; wheezing; nausea; and skin irritation
High levels of lead may cause anemia, weakness, and kidney and brain damage. Very high lead exposure can cause death.
Arsenic poisoning occurs over a brief period of time, symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. Long-term exposure can result in thickening of the skin, darker skin, abdominal pain, diarrhea, heart disease, numbness, and cancer.
High concentrations of ammonia in air causes immediate burning of the eyes, nose, throat and respiratory tract and can result in blindness, lung damage or death.
Tobacco smoke contains many chemicals that are harmful to both smokers and nonsmokers.

How are the spines on a cactus different from the leaves on an oak tree?
1. They provide nutrient intake
2. They provide heat exchange
3. They reduce water loss
4. They reduce oxygen release
Answers
Answer:
3.
Explanation:
because normal leaves transpire and release water where as spine don't transpire
Explanation: Cactus spines are basically modified leaves. They defend the cactus against herbivores but also assist in reducing water loss by reducing air flow to the cactus, which provides shade. And due to no leaves the cactus stems are what carry out photosynthesis. In simpler terms, the water on leaves can be lost due to evaporation, but cactus spines don’t.

2. In July, a student tested the soil in two plots and calculated the
concentration of nitrogen compounds present in each plot. The student
then planted 20 seedlings in the first plot and allowed them to grow.
Nothing was planted in the second plot. The student tested the soil in both
plots again after one month. The concentration of nitrogen compounds
had decreased in the first plot but had remained the same in the second
plot. Which of the following best explains the decrease in nitrogen
compounds in the first plot? *
A. The nitrogen compounds had broken down into elements.
B. The nitrogen compounds were absorbed by the seedlings for their growth.
C. The nitrogen compounds escaped through air pockets created by the seedlings'
roots.
D. The nitrogen compounds had evaporated because of the warm summer
temperatures.
Answers
Answer: B. The nitrogen compounds were absorbed by seedlings for their growth.
Explanation:
For the plant to have energy accessible when and where it needs it to maximize yield, nitrogen is essential. As proteins and enzymes control water and nutrient intake, this important nutrient is even present in the roots. Thus, option B is correct.
What nitrogen compounds were absorbed by the seedlings?Plants absorb ammonium and nitrate during the assimilation process, and these substances are then converted into organic molecules containing nitrogen, such as DNA and amino acids.
Plants may absorb substances from soils like nitrate, nitrite, ammonia, and ammonium, which are subsequently utilized to create proteins in both plants and animals.
Therefore, The nitrogen compounds were absorbed by the seedlings for their growth. After they reach three inches in height, seedlings should be fertilized; after that, they can get weekly fertilization until being transplanted.

Which is an example of genetic diversity? PLS HELP temperate rain forest and a tropical rain forest bees, jack rabbits, diamondback rattlesnakes bacteria, garter snakes, tigers variations in a flock of starlings
Answers
Answer:
temperate rain forest and a tropical rain forest bees.
Explanation:
The temperate rain forest and a tropical rain forest bees is the example of genetic diversity because the same organisms has different features which allows them to live in different climatic conditions due to their variation in genetics. The environment of temperate rain forest is different from tropical rain forest so the bees specie that live in both environment are different from one another in their genetic makeup and which is an example of genetic diversity.
3. What is the scientific term for a group of interacting individuals of the same type, living in the same area at the same time?
Answers
Answer: The scientific name is called POPULATION.
Explanation:
In basic ecological studies, POPULATION is defined as a group of interacting individual of the same type or species, living in the same area or habitat and at the same time.
Furthermore, to study a population of organisms, the different characteristics seen include:
--> Population size: This is important as it affects the survival of a given species in a habitat. A small population may be easily wiped out by events such a fire but a large population stands a better chance of survival.
--> Population frequency: This is simply how often the species occurs at different sites in a habitat.
--> Population density: this is the average number of individuals of a species per unit area of the habitat.
--> Percentage cover: This is the area of ground occupied by a given species in its habitat.
--> Distribution: This is the way in which individuals of a particular population are arranged in a habitat. They may be clumped, evenly spaced or randomly spaced.

To measure a population’s baseline genetic state, it must have _____________ to be in Hardy-Weinberg equilibrium.
A) Gene Flow
B) Random Mating
C) Selection
D) Mutations
Answers
Answer:
Random mating
hope it helps!
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).
To measure a population’s baseline genetic state, it must have random mating to be in Hardy-Weinberg equilibrium (Option B).
The Hardy-Weinberg principle state that the genetic variation in a population will remain constant across generations in the absence of different evolutionary forces.The Hardy-Weinberg assumptions include random mating, no mutation, no gene flow, infinite population size, and absence of selection.In consequence, random mating acts to prevent any change in the allele frequencies.In conclusion, to measure a population’s baseline genetic state, it must have random mating to be in Hardy-Weinberg equilibrium (Option B).
