The correct answer is: A) pontine respiratory centers
The respiratory centre in the pons is responsible for generating and maintaining the rhythm of respiration. Besides this elementary function, it also has the ability to adjust respiration rhythm in c response to physiological changes. Respiratory centre consists of three major respiratory groups of neurons:
• The dorsal respiratory group (DRG)- initiates inspiration (inhalation)
• the ventral respiratory group (VRG)-responsible for exhalation
• Pontine respiratory group- includes the pneumotaxic (controls both the rate and the pattern of breathing) and apneustic centers (promotes inhalation by sending signals to dorsal group).
Robert Steve and James are three new organisms ( lizard species ) Steve can breath under water he has scaly moist lizard skin a long strong tail and very sharp claws weighs 20 pounds and is 6ft long Steve prefers to eat small fish.
Robert can't breath under water has scaly dry lizard skin very sharp teeth and is very poisonous he has night vision weighs 5 pounds and is 2 ft long he mainly eats small bugs like lies and wasps.
James on the other hand is completely different he has is 10 feet long weighs 180pounds can run 5 miles per hour has powerful jaws that can break bones he has razor sharp teeth and claws and poisonous spit he has a smell radius of 15 miles and is a very heavy set he also prefers to eat big land animals like deer he's a Carnavor.
all of these Organisms are in a similar species (Lizard) and have similar characteristics ( Like scaly lizard skin and sharp claws) but they all have different traits and abilities.
I Hope this helped you.
Highly porous and permeable
Explanation:
Compared to other types of rock layers, an aquifer is highly porous and permeable.
Aquifers are always the target when prospecting for ground water in a formation.
- Porosity is the amount of void spaces in a rock.
- Aquifers are highly porous .
- Permeability is the inter-connectivity of the void spaces and their ability to transmit fluids.
- Aquifers have very high permeability compared to other rock types.
In terms of permeability and porosity, an aquifer is higher porous and permeable.

Answer;
-No more; no more
Compared with fraternal twins, identical twins are no more similar in physical appearance. Compared with unrelated look-alike pairs of individuals, identical twins report no more similar personalities.
Explanation;
-Compared with fraternal twins, identical twins are much more similar in extraversion, neuroticism and temperament.
-Since fraternal twins are 2 separate fertilized eggs, they usually develop two separate amniotic sacs, placentas, and supporting structures. Identical, or monozygotic, twins may or may not share the same amniotic sac, depending on how early the single fertilized egg divides into two.
Answer:
A sperm cell
Explanation:
A diploid cell has 46 chromosomes which is normally signified by somatic cells. Germ cells or gametes are haploid cells therefore they contain only 23 chromosomes. Male gamete contains 22 autosomes and one sex chromosome. That sex chromosome can be X or Y.
Female gamete does not have Y chromosome as a sex chromosome, it has only X chromosome as a sex chromosome. So Y chromosome in a human cell which have 22 autosomes determines that it is a male gametic cell or a sperm cell. Sperm cells that have a Y chromosome if fuses with female gamete produce male offspring(XY).
So the correct answer is- a sperm cell.
