The transcription factor that binds directly to the tata-box sequence is TFIID. This transcription factor (TFIID) is a macromolecular protein complex.
The TATA box is a fundamental nucleotide gene sequence that forms the eukaryotic core promoters, which are required to initiate transcription.
TFIID is a macromolecular protein complex (also called the RNA polymerase II preinitiation complex), which acts as a general transcription factor during the initiation of eukaryotic transcription.
TFIID recognizes and binds to the TATA box (core promoter) and also binds with different activator and repressor proteins in order to regulate the transcriptional activity.

Give two ways that differentiation is the same in plants and animal.
Differentiation in plants and animals involves the specialization of cells for specific functions, and it results in the development of different tissues and organs.
What is differentiation in plants and animals?Differentiation refers to the process by which cells become specialized in structure and function. In plants and animals, this process occurs during development and results in the formation of different types of cells, tissues, and organs.
During differentiation, cells undergo changes in gene expression, which leads to the production of different types of proteins and other molecules. These changes can be triggered by various signals, such as hormones, growth factors, and environmental cues.
In animals, differentiation occurs during embryonic development and results in the formation of different types of tissues, such as muscle, bone, and nerve tissue. In plants, differentiation occurs during both embryonic development and growth and results in the formation of different types of tissues, such as root tissue, leaf tissue, and stem tissue.

a human red blood cell is placed in a solution whose solute concentration is twice as great as the concentration of the cell cytoplasm. The cell membrane is selectively permeable allowing water but not the solutes to pass through. What will happen to the cell? a.) No change b.) the cell will shrivel because of osmosis c.) the cell will swell because of osmosis d.) the cell will shrivel because of active transport of water e.) the cell will swell because of active transport of water
Answer:
the cell will shrivel because of osmosis, moving to the region of higher concentration, and it shrivels due lost of water
As the troponin changes shape (due to binding calcium), it moves the ______ molecule to which it is attached, thus exposing the active sites on the G-actin molecules.
As the troponin changes shape (due to binding calcium), it moves the tropomysin molecule to which it is attached.
Once calcium binds to troponin and causes it to change it shape, it removes the tropomysin away from the binding site therefore effectively exposing the myosin binding sites.
This occurs during muscle contraction (movement) in the skeletal muscles.

Two brothers have thick hair that grows over their faces and most of their bodies.
This human disorder, called Ambra's Syndrome, shows X-linked dominant inheritance. The
mother of the boys is also affected by Ambra's Syndrome, although her excessive hair growth
occurs in various, scattered patches on her skin rather than a continuous coverage like her sons.
What is the most likely explanation for the patchy expression of hairlessness on the mother's
skin?
The most likely explanation for the irregular expression of hairlessness on the mother's skin is codominance
Codominance is a biological term to refer to the hereditary pattern that is characterized by:
In the heterozygous state, there is no recessive allele, but both behave as dominant. Codominance is characterized by the manifestation of both characteristics as dominant, without mixing.According to the above, the irregular expression of the lack of hair in the mother is a manifestation of the codominance of the hair gene and the hairless gene that do not mix but are seen independently.

Explanation:
Which are examples of active transport?
Select all that apply.
exocytosis
phagocytosis
diffusion
pinocytosis
Answer:
Exocytosis, phagocytosis, and pinocytosis
Explanation:
Active transport is when energy is used to move substances across the cellular membrane.
Exocytosis requires energy to remove materials from the cell; it is active.
Phagocytosis also requires energy; it is active.
Diffusion isn't active because it moves materials down their concentration gradient and therefore it doesn't require energy.
Pinocytosis is a form of endocytosis and requires energy; it is active.

Explain how water move from cell to cell in a leaf
Answer:
By osmosis, water enters the root and travels through the root cells until it reaches the xylem vessels. These canals carry water from the stem to the leaf. Transpiration is the process of removing water from the leaves of plants via evaporation.
Explanation:
Water moves from cell to cell in a leaf through a process called transpiration, facilitated by a combination of cohesion, adhesion, and capillary action in the plant's vascular system.
Transpiration: Transpiration is the process by which water vapor exits the leaf's stomata (tiny openings on the leaf surface) into the surrounding atmosphere. As water vapor evaporates from the cells within the leaf, it creates a lower pressure within the leaf's interior, drawing water molecules from neighboring cells.
Cohesion refers to the attraction between water molecules, causing them to stick together. Adhesion, on the other hand, is the attraction between water molecules and the surfaces of other materials, such as the walls of plant cells and the walls of xylem vessels. These properties work together to create a continuous column of water within the plant's vascular system, allowing water to move upward from the roots to the leaves.

7. Explain the following: All compounds are substances,
but not all substances are compounds."
Answer:
Below
Explanation:
"All compounds are substances, but not all substances are compounds."
In simpler terms, let us use an example. Look at the image below.
In a big circle, there are substances. And in the small there are compounds. Since the compounds are inside the big circle, they are compounds, but as you can see, the substances are not inside the compounds so they cannot be considered compounds.
If you think about it, a substance is anything. So would you think a bottle, for instance, is a compound? A compound is a mixture of molecules. And a substance is most likely a combination of atoms, which are elements.
