Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offsprin

g
An incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is
homozygous for blue feathers. Purple offspring result. Then, two of the purple offspring are crossed. According to the Punnett
square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete
dominance?

list 5 animals that live in the desert. Write a paragraph telling me how they can survive in this particular biome. What feature
NARA [144]

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.

Match the following: A) Smooth muscle B) Skin epidermis C) Tendon D) Cardiac muscle 17) Derived from mesenchyme. ___________ 18)
Stolb23 [73]

1.  

17) Derived from mesenchyme. C) Tendon  

Tendon is fibrous connective tissue (made of collagen) that connects muscle to bone.

18) Has a surface to which nothing is attached B) Skin epidermis.  

Epidermis is one of the three skin layers (other two are dermis and hypodermis) of skin that provides a barrier to infection from environmental pathogens.

9) Moves blood through the body. D) Cardiac muscle  

Cardiac muscle is found in heart which pumps blood through the whole body.

20) Moves food through the GI tract. A) Smooth muscle  

Motility through the GI tract is achieved by the contractions of ring smooth muscles (peristalsis).

2.  

21) Smooth muscle. B) Moderate regenerative ability.  

Cells called pericytes are cells that can regenerate smooth muscle cells. Also, smooth muscle cells themselves retain the ability to divide and thus regenerate (increase their own number).

22) Skeletal muscle C) Weak regenerative ability

Skeletal muscle contain  'satellite cells'-stem cells that have the ability to regenerate and repair the damaged fibres.  

23) Cardiac muscle A) Virtually no functional regenerative ability.  

When the cell of cardiac muscle-cardiac muscle cells die, they are not replaced.

24) Areolar connective tissue. D) Regenerates extremely well

Areolar connective tissue is loose connective tissue that hold organs in place. Fibroblasts are cells widely dispersed in this tissue

25) Tendons and ligaments. B) Moderate regenerative ability  

Healing or regeneration of ligaments and tendons can come from the surrounding soft tissues ("extrinsic healing"), or from the ligament /tendon itself ("intrinsic healing").

What are the changes that one can expect to observe as a plant tissue culture develops?
ahrayia [7]

The changes that one can expect to observe as a plant tissue culture develops is the development of new shoots and root.

<h3>What is a Culture?</h3>

This refers to the process in which microorganisms, living matter etc are grown in a specially prepared nutrient medium which are made up of different types of compounds.

In the case of a plant tissue culture, there will be new shoot and root formation due to the presence of nutrients in which the plants are exposed to for its growth and survival.

This is therefore makes changes in the shoot and root be the most appropriate choice.
