Do you think true water conducting tissue is a derived character of either embryophytes or green algae? Why or why not
Answers
Answer:
True
Explanation:
True water-conducting tissue is not a derived character from either green algae or embryophytes. Green plants consist of mostly aquatic “green algae” and a group known as embryophytes
Non-vascular plants are plants without a vascular system which is xylem and phloem.
Because green algae lack lignified water-conducting tissues, they cannot be tall as most vascular plants.
Green algae consist of several unrelated groups and they lack vascular tissue.
Most scientists would consider green
True water conducting tissue consist of xylem. It is a plant vascular tissue that moves water and dissolved minerals from the roots to the rest of the plant and also provides physical support.
Xylem tissue comorises of a different specialized, water-conducting cells commonly called tracheary elements
Conclusively, Since water conducting tissue is xylem which is absence in Green algae and embryophytes, they can therefore not be regarded as both.

compact bone question 9 options: has a brace-like arrangement of trabeculae. all of the choices are correct. is composed of tubular units called osteons. is located deep to spongy bone in the diaphysi
Answers
The correct answer is that compact bone is composed of tubular units called osteons.
Compact bone is characterized by a dense and rigid structure that has a brace-like arrangement of trabeculae. This type of bone is located deep to spongy bone in the diaphysis.
Compact bone is the densest and strongest type of bone found in the human body. It is composed of tubular units called osteons, which are arranged in concentric circles around a central canal. Each osteon is composed of concentric layers of hard mineralized tissue known as lamellae. The lamellae are connected by tiny channels, called canalsiculi, which allow for the passage of blood vessels, nerves, and other small molecules.
Compact bone is located deep to spongy bone in the diaphysis of long bones, providing a strong and rigid structure to the bone. It also has a brace-like arrangement of trabeculae that provides extra strength and support for the long bones. Compact bone helps to protect the internal structures of the body from damage or injury.

Answers
This instability arises due to the delicate balance between the strong nuclear force, which holds the nucleus together, and the electromagnetic force, which repels positively charged protons.
When there are too many protons relative to neutrons, the repulsive electromagnetic force becomes dominant, leading to an unstable nucleus that seeks to achieve a more balanced state by emitting radiation.
The spontaneous decay of a radioactive isotope is called natural transmutation. Natural transmutation refers to the process where an unstable nucleus spontaneously undergoes radioactive decay without any external influence.During natural transmutation, the unstable nucleus releases particles or electromagnetic radiation to reach a more stable configuration. This process is fundamental to the concept of radioactive decay and plays a significant role in understanding the behavior of radioactive isotopes in various scientific and practical applications.

what is the role of dna molecules in the synthesis of proteins
Answers
DNA, Proteins, Synthesis, Molecular DNA molecules play a key role in the synthesis of proteins, as they act as the template for protein production.
This process is known as transcription and is carried out by enzymes that interact with the DNA and carry out the process of protein synthesis.
During transcription, a strand of DNA is used to create a strand of messenger RNA (mRNA). The mRNA then carries the genetic instructions from the DNA to the ribosomes, where the mRNA is used to create the protein.
The protein created by the ribosome is a direct translation of the genetic instructions encoded in the DNA molecule. This process is known as translation.
In summary, DNA molecules provide the genetic instructions needed to create proteins, and this process is carried out through transcription and translation.

; charge =+e) placed inside the membrane. (a) Number Units (b) Number Units
Answers
(a) The magnitude of the electric field within the cell membrane is 7.1×10⁶ N/C.
(b) The magnitude of the electric force exerted on a potassium ion (K+) placed inside the membrane is 1.6×10⁻¹⁹ N.
(a) The magnitude of the electric field (E) within a capacitor can be determined using the formula E = σ/ε₀, where σ is the charge density and ε₀ is the permittivity of free space. Given a charge density of 7.1×10⁻⁶ C/m², and knowing that ε₀ = 8.85×10⁻¹² C²/Nm², we can calculate the electric field as follows:
E = (7.1×10⁻⁶ C/m²) / (8.85×10⁻¹² C²/Nm²) = 8.03×10⁵ N/C.
Therefore, the magnitude of the electric field within the cell membrane is 8.03×10⁵ N/C.
(b) The electric force (F) experienced by a charged particle inside the membrane can be calculated using the formula F = qE, where q is the charge of the particle and E is the electric field. For a potassium ion (K+) with a charge of +e, where e is the elementary charge (+1.6×10⁻¹⁹ C), and using the electric field calculated above (E = 8.03×10⁵ N/C), we can find the magnitude of the electric force:
F = (+1.6×10⁻¹⁹ C) × (8.03×10⁵ N/C) = 1.29×10⁻¹³ N.
Hence, the magnitude of the electric force exerted on a potassium ion (K+) placed inside the membrane is 1.29×10⁻¹³ N.

How do you find the sequence of bases on a DNA strand?
Answers
Answer:
First of all, make sure that you indicate on the question itself the directionality of the sequence: which makes this (by convention) 5′ AGCTCAG 3′. We assume that any sequence written without the 5′ and 3′ designations is from the sense strand, and reads from 5′ on the left to 3′ on the right. Therefore, the complementary sequence, which is being asked for, must go from 3′ to 5′ as matched up (because it runs in the opposite direction). So, this is 3′ TCGAGTC 5′. It is true that we often write sequences without the formal directionality indicators, and if so, we do it from 5′ to 3′. However, if you put “CTGAGCT” as your answer, experience tells me that you have a very good chance of getting it marked wrong (unless your instructor is testing you all with a little tricky questioning).

How do you think that Karl von
Frisch gathered information
about the honey bee's
behaviour?
Answers
Answer:
Karl von Frisch is best known for two major discoveries about honey bees. First, he demonstrated that honey bees have color vision, and published these findings in 191*. Second, in 193* he showed that honey bees use a dance language to communicate food locations to other bees.
Explanation:
Figure 1. Grids for the color vision test. The training color, marked with T, is blue in both cases; all other squares are shades of gray. The left box shows how the grid appears to an animal with color vision. The right box shows how the same grid may appear to an animal without color vision. The training square appears to be the same shade of gray as other squares in the grid. If the test animal cannot see in color, it will confuse the training square with other squares matching its shade of gray.
This clever test for color vision can be applied to any animal which can learn to recognize a feeding station using visual patterns.
The dance language
von Frisch observed that once one honey bee finds a feeding station, many other soon appear at the same station. This suggests that the first bee recruits other bees to the food. How might honey bees recruit help in collecting food? von Frisch¹s discovery of the dance language of the honey bee required careful determination of the correlations between movements of bees inside the hive and the locations of feeding stations. He found two types of dance. The round dance (Figure 2A) causes bees to look for food a short distance (up to about 50 meters) from the hive. The waggle dance (Figure 2B) tells bees the direction and distance to fly to find more distant food sources. Scout bees use these dances to recruit assistance in collecting food resources.

Answers
The similarity in early embryonic development among different vertebrate species, such as the presence of tails and gill slits, suggests a common evolutionary ancestry and shared developmental pathways.
The observation that vertebrate embryos exhibit similar features during early development provides evidence for the concept of evolutionary conservation. This similarity is known as embryological homology and indicates that different vertebrate species share a common ancestry and evolutionary history.
During early development, vertebrate embryos go through a stage called the pharyngula stage, where they possess certain characteristics such as tails and gill slits. These features are remnants of ancestral structures that were once functional in the common ancestor of these species. For example, the presence of gill slits in the embryos of different vertebrates reflects their shared aquatic ancestry and indicates a common developmental pathway for the formation of respiratory structures.
The conservation of these developmental features suggests that there are shared genetic and molecular mechanisms that govern embryonic development across vertebrate species.
These shared developmental pathways are controlled by genes and regulatory factors that have been preserved throughout evolution.

The role of hemidesmosomes - hemidesmosomes are involved in the attachment of epithelial cells to the basement membrane in tissues and organs. They have a half of a desmosome-like structure and have a similar composition of cadherins, integrins, and intermediate filaments.
The role of tight junctions - Tight junctions seal neighboring cells in an epithelial layer, preventing water, ions, and other solutes from passing freely through the intercellular space. The tight junctions seal the epithelium together, allowing a layer to function as a barrier, such as in the skin or intestinal tract.

Answers
The cell needs to maintain a higher concentration of NADPH to ensure that these reactions can continue to occur.
The intracellular concentration ratios of the nicotinamide nucleotides are dependent on the metabolic state of the cell. In oxidative metabolic reactions, NAD+ is used as an electron acceptor and is reduced to NADH. In reductive metabolic reactions, NADPH is used as an electron donor and is oxidized to NADP+.
a. [NAD+]/[NADH]: This ratio is typically >1 in the cell. This is because NAD+ is required for oxidative metabolic reactions, such as glycolysis and the citric acid cycle, which are constantly occurring in the cell to produce energy. Therefore, the cell needs to maintain a higher concentration of NAD+ to ensure that these reactions can continue to occur.
b. [NADP+]/[NADPH]: This ratio is typically <1 in the cell. This is because NADPH is required for reductive metabolic reactions, such as fatty acid synthesis and the pentose phosphate pathway, which are also constantly occurring in the cell.
