Answer:
False.
Explanation:
Protons are positively charged, so having more protons would make an atom positively charged. Electrons are negatively charged.
Answer:
A) polar
Explanation:
Polar molecules contains partial positive and partial negative charge as in all polar molecules two atoms have unequal sharing electron. Due to unequal sharing of electrons, one atom that attracts valence electrons strongly gains positive charge and other gain negative charge.
For example water, water is a polar molecule having partial negative and partial positive charge because the oxygen atom in water attracts electrons more strongly than the hydrogen atoms.
Hence, the correct answer is "A) polar".
It is the motor cortex of the brain that controls the voluntary movements of the body. It is in the rear part of the frontal lobe and is a region in the cerebral cortex. It is responsible for planning, control and the execution of the voluntary movements in the body.
Answer: Provides support for the blade of the leaves.
Explanation:
Vascular tissues are conducting tissues formed from specialized cells . The two conducting vascular tissues in plants are xylem and phloem.
Xylem tissue transport water and nutrients from plant roots to all part of the plants. Phloem transport sugars. It also provide structural support for plants. Vascular tissues run through the veins of the leaves and provide support. Vascular tissues are found in vascular plants.
Embryology, the study of the development of the anatomy of an organism to its adult form, provides evidence for evolution as embryo formation in widely-divergent groups of organisms tends to be conserved. ... Another form of evidence of evolution is the convergence of form in organisms that share similar environments.
