Answer:
Chloroplast
Explanation:
Chloroplasts are organelles found in green plants. They are the sites of photosynthesis. Chloroplasts contain chlorophyll, a photosynthetic pigment that traps light energy. This energy is used to power a series of reactions that convert water and carbon dioxide into sugars.
The independent variable is the seeds.
Answer:
the SRY gene.
Explanation:
The SRY gene was found within the minimum region of Y-specific DNA required for male development. Confirmation of its role was found by the analysis of XY female patients with mutations within this gene. A mouse has been an important working model to study the process of mammalian sex determination.
Answer: 1. The answer lies with carbon's unique properties. Carbon has an exceptional ability to bind with a wide variety of other elements. Carbon makes four electrons available to form covalent chemical bonds, allowing carbon atoms to form multiple stable bonds with other small atoms, including hydrogen, oxygen, and nitrogen. 2. Carbon is used by plants to build leaves and stems, which are then digested by animals and used for cellular growth. In the atmosphere, carbon is stored in the form of gases, such as carbon dioxide. It is also stored in oceans, captured by many types of marine organisms. 3. When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and climate change. brainliest

Answer:
Duplication of Hox genes made increased morphological complexity possible.
Explanation:
- The hox gene cluster consists of a group of related genes that function to controls the basic body plan of an embryo and also define the head to the tail axis.
- These are mainly responsible for ensuring the correct position of al the structures in the body.
- Since the anterior-posterior axis all the vertebrates are established by these hox genes this points out to the fact that common information is needed amongst all he vertebrates to define the various morphological variations that occurred.
- The hox genes have shown duplication in the course of evolution and they have undergone a four-fold duplication which has led to the generation fo different structures in the various organism and is thus responsible for the increased morphological complexity.
