Answer:
Type A is a lens galaxy and Type B is an irregular galaxy.
Explanation:
Type A: Lens galaxies' have a large flattened core. lenticular galaxies have a shape reminiscent of a lens (hence the alternative name).
Type B: Irregular galaxies' do not have a regular shape. An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. Irregular galaxies do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.

Which is the last structure to contact sperm before it leaves the body?
penis
sperm duct
testes
urinary bladder
Answer:
A is correct
Explanation:
Urinary bladder is the last structure to contact sperm before it leaves the body.
What are the functions of urinary bladder?The urinary bladder, or simply bladder, is a hollow organ in humans and other vertebrates that stores urine from the kidneys before disposal by urination. In humans the bladder is a distensible organ that sits on the pelvic floor.
The urine formed by the nephrons of the kidneys is transported to the urinary bladder for storage before it gets expelled through the urethra. The urinary bladder is a sac that serves as a reservoir for urine.
The urinary bladder is a temporary storage reservoir for urine. It is located in the pelvic cavity, posterior to the symphysis pubis, and below the parietal peritoneum. The size and shape of the urinary bladder varies with the amount of urine it contains and with the pressure.

During a large thunderstorm, you hear and feel the thunder. Draw a representation of the sound wave produced. Your model should account for the energy and patterns of the wave.
Answer:
Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
Explanation:
This is why we hear and feel them!
Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
What is Sound waves?A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid matter).
Pressure waves are produced when an object vibrates, such as a ringing phone, and these waves are known as sound waves. The surrounding medium's particles are disturbed by the pressure wave, and those particles disturb the particles next to them, and so on.
Like ocean waves, the disturbance's pattern causes outward movement in all directions. Usually in all directions and with decreased intensity as it gets further away from the source, the wave transmits the sound energy through the medium.
Therefore, Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).

Why does your respiration increase during exercise?
Answer:
Explanation:
When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.

Answer:
There is reduced cellular respiration or energy production if only fermentation is used and this will lead

What is the difference between primary waves and secondary waves
Answer:
Primary and secondary waves both are body waves of seismic waves. Primary waves or pressure waves are compression waves and secondary waves are shear waves. These waves are represented by P and S waves respectively.
Differences:
P waves are smaller in size but travel faster, however, cause less damage whereas S waves are greater in size cause more damage, and travel slower.
P waves move in a push-pull pattern and travel through different mediums like solids, liquids, and gases, whereas S waves move in an up-and-down pattern and travel only through one medium that is a solid medium.
A lack of sufficient information and data of population size and growth of Atlantic cod is one of many reasons to explain the mismanagement and current decline in Atlantic cod population, Based on your understanding of logistic growth model, if one day atlantic cod recovered in Gulf of Maine, you would recommend to maintain the cod population at _______________ point of the logistic growth model at which population would show the fastest growth rate.
ANSWER: LOG PHASE/POINT
EXPLANATION: The log phase of logistic population growth witness the fastest growth rate. It's the phase where there is rapid growth exploiting the high resources supplied.
Moreso, the population continues to grow rapidly approaching the carrying capacity (i.e the highest population size that the resources available in the ecosystem can sustain). On getting to the carrying capacity the ecosystem can withstand, the growth rate adjusts and move inline with the carrying capacity. It's also referred as exponential phase.
