Answer:
Option (D).
Explanation:
Recombination frequency nay be defined as the the frequency of crossover of a single chromosome during meiosis. The maxiumum recombination frequency is 50%.
Genes that has recombination frequency nearly equal to 50% are considered as unlinked genes. Unlinked genes cannot undergo the recombination process and may have equal chances to inherit together or can inherit separately in the next generation.
Thus, the correct answer is option (D).
Answer: conditioned
Bobby touches his newborn brother's palm, and his little brother takes hold of Bobby's finger and will not let go. This is known as the conditioned reflex.
Explanation:
A conditioned reflex is a response or behaviour learned after birth. So, once the newborn acquires this learned response, they can perform them even without thinking about it.
Thus, Bobby's brother (the newborn) holding on to his finger and not letting go shows that it is a conditioned reflex
Answer:
False
Explanation:
Plants, based on whether they can conduct water and nutrients, are classified into vascular and non-vascular plants. Vascular plants also called TRACHEOPHYTES are plants that possess certain special tissues called vascular tissues used for conducting water and nutrients in a plant. These conducting tissues are xylem and phloem.
On the other hand, non-vascular plants do not possess vascular or conducting tissues, hence, they cannot transport water and nutrients throughout the plant. Hence, such plants are naturally found in moist areas e.g. mosses. Therefore, based on the question asked, the answer is FALSE.
Answer:
A device to measure the dimensions of a object
Explanation:
Answer:
As a cell grows in size, the surface area gets bigger, but the volume gets bigger faster. Thinking about this as a ratio (division), the volume is the denominator and the surface area is the numerator. If the volume is getting very big, then the ratio itself will be getting very small.
