<span>d. neither of these will cross a plasma membrane.
Glucose cannot diffuse across a plasma membrane as it is polar. Since the question doesn't specify the type of diffusion, simple diffusion is assumed.
If you count facilitated diffusion, then A is the answer.</span>
5 desert animals are camel, sand cat, desert tortoises, desert lizards and the great road runner.
<u>Explanation:</u>
- Camel has several physiological and behavioral adaptations that help them survive the extreme conditions of the desert. They have flat feet to help them spread their weight in the sand.
- They have thick eyelashes and closeable nostrils to prevent the entry of sand. They store fat on their humps that supplies energy during long journeys and has a long large intestine which increases water reabsorption.
- Sand cat is similar to the domestic cat in basic appearance but has several adaptations enabling it to survive in the desert. Their paws are covered with thick and long hairs to protect the feet from the heat. They have thick fur that acts as an insulting surface during hot days and cold nights.
- Desert tortoises have excellent water storage capacity. Their bladders are larger than normal and can carry extra water. They have strong feet which helps them to dig holes in the sand and access rainwater.
- Desert lizards can drink water through skin. They do it by a process called cutaneous water acquisition and it helps them to gather water obtained from rainfall, damp sand and pools.
- Great roadrunner has peculiar adaptations. The digestive system of the bird retrieves water from the feces as it is in the excretory canal.
Answer:
Explanation:
1. Progeny observed in the experiment is calculated by adding all the progeny numbers observed in the :
TIME TO FRUIT TENDRIL SIZE FRUIT COLOR NUMBER
Normal normal dark 370
normal normal light 32
early normal light 971
early normal dark 28
early reduced dark 25
early reduced light 483
normal reduced light 36
normal reduced dark 810
TOTAL
PROGENCY <u>2755</u>

<u>
</u>
2. The locus in the center is TIME TO FRUIT. Tendril size is at the beginning of the locus and the distance between the locus B and locus C is R2

A nucleotide is the basic building block of nucleic acids
Answer: c) Some organisms rely on energy captured from inorganic compounds to drive basic biological processes.
Explanation:
Deep-sea hydrothermal vents are hot spots of geothermal water. The organisms living in deep-sea vents cannot obtain energy from sunlight. They are dependent on chemosynthesis, which involves the utilization of inorganic substances to produce organic substances, which allows their survival and act as a source of energy. In the given situation, bacteria present on the surface of mussels are capable of chemosynthesis also the mussels are dependent upon inorganic hydrogen in seawater. Thus chemosynthesis supports the survival of organisms living in the deep sea vents.
