Answer:
Respiration begins at the nose or mouth, where oxygenated air is brought in before moving down the pharynx, larynx, and the trachea. The trachea branches into two bronchi, each leading into a lung. Each bronchus divides into smaller bronchi, and again into even smaller tubes called bronchioles.

3. What can the reader reasonably conclude based on the information in this passage?
A. Animals in the rain forest are strictly independent of each other.
B. Animals in the rain forest have found ways to thwart their competition and survive
C. All animals in the rain forest have the same adaptations.
D. Animals in the rain forest all need the same amount of sunlight.
i think answer is D animal in the rain forest
All animals in the rainforest have the same adaptations. Therefore, option C is correct.
What is adaptation?A physical or behavioral characteristic of an animal that enhances its ability to survive in its environment is known as an adaptation.
To put it another way, an adaptation is something a person does or has on them that makes it easier for them to locate food, water, mates, and shelter. The structural adaptations made by some plants to survive in hot, dry deserts are one illustration of this.
Animals can defend themselves against predators and extreme weather by adapting. Numerous birds may conceal themselves under long grass, while weeds, insects, and other creatures can alter their colour to blend in. Predators find it challenging to locate them in search of food as a result. Hence, option C is correct.

Answer:
Invasive species
Explanation:
You are studying a population of sexual, diploid insects. One particular trait, wing size, is controlled by a single locus with two alleles. The allele for narrow wing size is dominant (N) and the allele for wide wing size is recessive (n). The population you are studying is comprised of 97 individuals with the NN genotype, 52 individuals with the Nn genotype and 50 individuals with the nn genotype. What is expected frequency of the dominant allele (A1) after selection
Answer:
The expected frequency of the dominant allele, N is 0.70
Explanation:
Total number of individuals in the insect population = 97 + 52 + 50 = 199
From Hardy-Weinberg equation, p2 + 2pq + q2 = 1; also p + q = 1
The frequency of dominant allele, N = p
Frequency of dominant NN genotype individuals = p2
From the given data: the population is comprised of 97 individuals with the NN genotype, 52 individuals with the Nn genotype and 50 individuals with the nn genotype.
Frequency of NN genotype individuals p2 = number of individuals with NN genotype ÷ total insect population
p2 = 97/ 199
p2 = 0.487
p = 0.697 = 0.70
Therefore, the expected frequency of the dominant allele, N is equal to 0.70
The calcium ion passes easily through the membrane of one cell but
cannot cross the membrane of a second cell. Which part of the plasma
membrane allows this substance to cross? *
- Phosphate groups of the phospholipid bilayer allow the ions to cross.
- The fatty acid tails of the phospholipids allow the ions to cross.
- Protein channels in the plasma membrane allow the ions to cross.
- Carbohydrate groups on the membrane allow the ions to cross.
Answer:
Protein channels in the plasma membrane allow the ions to cross.
Protein channels which are present in the plasma membrane of the cell allow the ions to cross the plasma membrane. Thus, the correct option is C.
Channel protein is a kind of protein which is found embedded in the plasma membrane of the cell. Channel proteins function similar to a pore and it allows the diffusion of small ions and water molecules through them. Channel proteins are lipoproteins and these are synthesized in the rough endoplasmic reticulum of the cell near the nucleus.
Ion channels are the transmembrane proteins whose canonical function is the transport of ions and molecules across the plasma membrane to regulate cell membrane potential and also play an essential role in neural communication, nerve conduction, and muscle contraction in the body.
Therefore, the correct option is C.
