Answer:
D. They can cause changes in body shape
Explanation:
Homeotic genes are evolutionarily conserved genes that regulate the development of body parts. Mutations in these genes can eventually produce changes in body patterning. In animals, for example, Hox genes are homeotic genes that encode transcription factors which contain evolutionary conserved DNA binding region (i.e., homeodomain). Both in invertebrates and vertebrates, Hox genes (Hox) play key roles in global body patterning. In plants, MADS-box genes are well-known homeotic genes that have key roles during embryo, inflorescence and flower development.
Answer:
d. Simple Columnar Epithelia
Explanation:
The simple columnar epithelium is an epithelial tissue that has a single layer of nonciliated cells. The cells look like columns and have oval nuclei near their base. This type of epithelial tissue has microvilli at the apical surface of their columnar epithelial cells. These microvilli are the fingerlike cytoplasmic projections that serve to increase the surface area for absorption.
Simple columnar epithelium makes the linings of the gastrointestinal tract, specifically from the stomach to anus where they live the cavities of these organs.
Answer:
I just put
The small mass got warmer than the large mass.
Explanation:
PLEASE MARK ME AS BRAINLIEST
The leaf support should actually be water. if in hot and dry weather, the leaf loss so much water that will make the plant cells flaccid and wilt.
