One adaptation to life in flowing water is _____.
valkas [14]

One adaptation to life in flowing water is - breeding in oceans

Adaptation is not a quick process but rather it is a slow and time taking process. It can be defined as an evolutionary process where an organism becomes increasingly well suited to living in a particular habitat. It is a feature of an organism that enables it to live in a particular habitat.

Gelneren [198K]

The common atrium is subdivided into a left and right atrium by an interatrial septum, which consists of two parts: the septum primum and the septum secundum that partially overlap.

What is septum primum and septum secundum?

  • The septum primum, which divides the right from the left, is a structure inside the primitive atrium.
  • In the direction of the endocardial cushions, this septum descends.
  • The foramen primum, a hole in this septum, keeps the blood flowing through the heart.
  • The foramen secundum develops as the foramen primum shrinks in size.

What is the purpose of septum secundum?

  • A muscular flap called the septum secundum plays a significant role in heart growth.
  • It has a semi-lunar form and develops from the atrium's upper wall to the right of the septum primum and ostium secundum.
  • It is crucial for the foramen ovale to close after birth.

Which of the following chemicals opens us binding sites allowing muscle filaments to connect to each other? Select one:
HACTEHA [7]

Answer:

The correct answer will be option-D.

Explanation:

Calcium plays an important role in muscle contraction as they are released from the sarcoplasmic reticulum after they receive electric impulse.

Calcium triggers the muscle contraction cycle as these calcium ions bind to the troponin-tropomyosin complex. This binding exposes the myosin-binding site on the actin on which high energy myosin binds and cross-bridge is formed.

This cross-bridge formation causes the contraction of the sarcomere and therefore muscle contracts.

Thus, option-D is the correct answer.

The genes dumpy (dp), clot (cl), and apterous (ap) are linked on chromosome II of Drosophila. In a series of two-point mapping c
Dmitrij [34]

Answer:

The order of genes is- dp-cl-ap

Explanation:

The genes a be mapped on chromosome on the basis of the recombination frequency as the recombination shows that is the genes are linked or not.  In genetic mapping, 1 per cent recombination frequency is considered as 1 cM or map distance.

In the given question, the three gene distance are provided on the basis of which the gene can be mapped in the following manner:

1. Take the higher value of gene distance that is 42 m.u and plot them on the line,

2. now place second-highest value on the line that is 39 m.u.

3. The gene will be arranged in the order of dp-cl-ap.

4. dp--³---cl-----------³⁹---------------------ap.

Thus, dp-cl-ap is correct.
