Answer:
While humans, as well as other vertebrates, have a closed blood circulatory system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open circulatory system containing a heart but limited blood vessels.
Explanation:
The causitive agent of the cohesion-tension model of xylem transport is transpiration. During the process of transpiration, water vapor is lost from the stomata of the leaf. To replace this water, water from adjacent cells is withdrawn. The water molecules stick together due to cohesion and are transported upwards through the stem in the form of a stream.<span />
The correct answer is D) GCC AGC UCA CUA
A process in which information from a DNA is copped into a messenger RNA (mRNA) is called transcription. During transcription in genetic codes present on the DNA is copied on the mRNA. In the given question the DNA has codes CGG TCG AGT GAT thus, on mRNA the corresponding codes will be GCC AGC UCA CUA because A pairs with U and G pair with C and vice-versa.
Answer:
Gravitropism
Explanation:
Plants can respond to gravity, water, touch, and light in their environment. Plant parts can grow with or against gravity. This type of tropism is called gravitropism. Roots of a plant grow downward and exhibit positive gravitropism.
