Which of the following is not a function of a vertebrate’s endoskeleton?
a.) Increase speed of digestion
b.) Protect major organs
c.) Offer support and structure
d.) Connect with muscles to create movement
Increase speed of digestion is not a function of a vertebrate’s endoskeleton. So, the correct option is (A).
What is Endoskeleton?
The rigid part which provides internal support of the structure is called endoskeleton which develops from endoderm and is called a living structure. Some examples of endoskeleton are cartilage, bone etc. The hard part that is on the outside of the body that protects the soft tissues and muscles is called the exoskeleton.
Vertebrates are animals that have a backbone and an endoskeleton which is a skeleton inside their body while invertebrates are animals that do not have a backbone. Invertebrates may have a skeleton on the outside of their body called an exoskeleton, while some invertebrates have no skeleton at all.
It protects major organs, offer support to the structure, connect the muscles to create movement.
Thus, Increase speed of digestion is not a function of a vertebrate’s endoskeleton. So, the correct option is (A).

Name three reasons why the atmosphere is important to life on earth and explain your reasoning.
The atmosphere ensures that all living things can carry out daily processes that are vital to survival, such as breathing. Photosynthesis, for example, could not be possible without an atmosphere, because all of the gasses in our atmosphere stay there due to Earth's gravity.
The atmosphere is vital because it plays a role in the water cycle as well, allowing rain to keep falling and giving life-giving water to organisms that need it.
Life would not be possible without an atmosphere on this planet, along with other vital things, like gravity, sunlight, and water.
Flowering Locus C (FLC) is a gene that is responsible for flowering in certain plants. FLC is expressed in new seedlings, which prevents flowering. Upon exposure to cold temperatures, FLC expression decreases and the plant flowers. FLC is regulated through epigenetic modifications. What type of epigenetic modifications are present in new seedlings and after cold exposure
Answer:
- New seedlings: histone acetylation
- After cold exposure: histone methylation
Explanation:
Vernalization is an adaptive mechanism whose objective is to ensure that flowering occurs only after winter (i.e., after cold conditions). In certain plants, this process (vernalization) suppresses the expression of genes that encode repressors of flowering. In Arabidopsis, vernalization is associated with histone modifications at FLC chromatin. The FLOWERING LOCUS C (FLC) is a MADS-box gene that acts as a repressor of flowering in Arabidopsis. Epigenetic modifications control the expression of the FLC gene. The FLC gene is expressed at low temperatures due to histone acetylation at FLC chromatin, and thereby the expression of FLC mRNA transcripts ensures that the Arabidopsis plant cannot flower. Subsequently, as the Arabidopsis plant is exposed to cold, FLC is repressed by the accumulation of trimethylation on lysine 27 of histone 3 (H3K27me3), thereby allowing it to flower when temperatures become warmer.
