Image is not available in the question so, the correct image is attached below.
Answer:
D. codes for a specific trait
Explanation:
chromosome is defined as a DNA molecule found in the nucleus of most living cells which carry genes and transfer the genetic information.
The part labelled b in the image is gene. The function of gene is to code for a specific trait.
Genes are responsible for carrying traits that form the genotype and phenotype of an organism. where genotype shows the differences in genetic formation and phenotype shows observable characters in an individual such as color, height and features.
Hence, the correct option is D.
Answer:
b. False
Explanation:
A scientific theory must have strong support from testable facts that are confirmed (or rejected) by observational and/or experimental procedures. The scientific method is a rigorous process that consists of arising a conjecture (hypothesis) which can be subsequently used to make predictions from its logical consequences, and finally to obtain information from empirical observations/experiments in order to obtain a conclusion about the veracity of the scientific claims (i.e., a hypothesis must be testable). In consequence, a scientific theory can not be based only on 'light' conjectures, but trustworthy observational data from the real world.
Explanation:
The planet Mars has two moons. Phobos and Delmos (i) phobos has period `7` hours, `39` minutes and an orbital radius of `9.4 xx 10^(3) km`. Calculate the mass of Mars. (ii) Assume that Earth and mars move in a circular orbit around the sun, with the martian orbit being `1.52` times the orbital radius of the Earth. What is the length of the martian year in days? `(G = 6.67 xx 10^(-11) Nm^(2) kg^(-2))`
Osmosis
Osmosis is movement of a solvent, across a semi-permeable membrane.
