a. unrelated to age.
b. usually correlated with density-independent causes.
c. higher in the post-reproductive than in the pre-reproductive years.
d. lower after the organisms survive beyond the earliest age groups.
e. more or less constant throughout their lives.
The death rate of organisms in a population exhibiting a type III survivorship curve is
d. lower after the organisms survive beyond the earliest age groups
A survivorship curve is a graph that displays the number or percentage of individuals for a certain species or group that survive to each age (e.g. males or females). Based on a life table, survival curves for a certain cohort (a collection of people about the same age) can be created.Which of the three survivorship curve kinds are they?
People with Type I survivability have high survival rates throughout their whole life spans. The proportion of deaths over time is constant in populations with Type II survival. Young-onset mortality is extremely high in populations with Type III survival.

Which item is an example of a specialized cell found in plants?
OA. Red blood cell
OB. Osteocyte
OC. Tracheid
OD. Nerve cell
The specialized cell found in plants is the tracheid. The correct option is C.
What is tracheid ?
A tracheid is a type of elongated, dead, water-conducting cell found in the xylem tissue of vascular plants. They are the most primitive type of water-conducting cell in plants and are present in most gymnosperms and some ferns.
Tracheids are characterized by their long, narrow shape and thick, lignified cell walls, which provide support to the plant. The walls of tracheids have small pits that allow water to move from one tracheid to the next. These pits are bordered by thin, un-lignified regions of the cell wall called the pit membrane

lactose is a disaccharide made up of the monosaccharides glucose and galactose. lactase is the enzyme which breaks down lactose into it's individual monosaccharides. what do you think is the purpose of having a set up with lactose lactase enzyme?
The purpose of having a set up with lactose and lactase enzyme is to break down lactose into its individual monosaccharides, glucose and galactose.
This is important because some people have a lactose intolerance, which means they cannot properly digest lactose due to a deficiency in lactase enzyme. By breaking down lactose into glucose and galactose, these individuals are able to properly digest and absorb the sugars without experiencing these unpleasant symptoms.
Additionally, lactose is a major source of energy for infants who are breastfed, as breast milk contains lactose. Lactase enzyme is present in high amounts in the intestines of infants, allowing them to properly digest and absorb the lactose in breast milk.
Overall, the set up with lactose and lactase enzyme is important for proper digestion and absorption of lactose, and for providing energy for infants who are breastfed. It also helps individuals with lactose intolerance to avoid uncomfortable symptoms and maintain a balanced diet.

noted for increases in blood pressure. a. sympathetic b. parasympathetic c. both a and b d. none of the above
The correct answer is a) sympathetic. The sympathetic nervous system is responsible for the "fight or flight" response in the body, which can lead to increases in blood pressure.
It triggers the release of adrenaline and norepinephrine, which can cause blood vessels to constrict and the heart to beat faster and stronger. The parasympathetic nervous system, on the other hand, is responsible for the "rest and digest" response, which can lead to decreases in blood pressure. It promotes relaxation and slows down heart rate and breathing. Therefore, option c) both a and b and d) none of the above are not correct as they do not accurately reflect the role of each nervous system in regulating blood pressure.

the baseline level of contraction of blood vessels (without any neural, hormonal, or paracrine input), is known as
The baseline level of contraction of blood vessels without any neural, hormonal, or paracrine input is known as vascular tone.
Vascular tone refers to the intrinsic level of constriction or contraction present in blood vessels at rest, in the absence of any external influences. It is maintained by the coordinated action of smooth muscle cells within the vessel walls.
Vascular tone plays a crucial role in regulating blood pressure and blood flow throughout the body. Without any neural, hormonal, or paracrine input, the smooth muscle cells in blood vessel walls maintain a certain level of contraction, keeping the vessels partially constricted.
This baseline level of constriction is important for maintaining vascular resistance and ensuring adequate perfusion of organs and tissues.
Various factors can influence vascular tone, such as neurotransmitters, hormones, and local chemical signals, which can either increase or decrease the degree of constriction.

Lycopodium is more developed than Marchantia.
Lycopodium is more developed than Marchantia because it has vascular tissue for water and nutrient transport, unlike the non-vascular Marchantia.
Lycopodium, commonly known as clubmoss, is more developed than Marchantia, a liverwort, primarily due to the presence of vascular tissue in Lycopodium.
This vascular tissue, composed of xylem and phloem, allows for efficient transport of water, nutrients, and sugars throughout the plant, contributing to its growth and overall complexity.
In contrast, Marchantia lacks vascular tissue and relies on diffusion and osmosis for nutrient and water transportation. Additionally, Lycopodium exhibits a more complex life cycle and a better-developed sporophyte generation, whereas Marchantia has a simpler, less evolved life cycle with a dominant gametophyte generation.

In David Gallo's talk "Underwater Astonishments," he discusses various adaptations of underwater creatures, focusing on squid and octopus.
1. Regarding the fighting squid, the adaptation Gallo mentions is the ability to change color and pattern rapidly. This adaptation is useful for male squid because it helps them communicate their intentions, establish dominance, and deter rivals during confrontations.
2. When talking about the octopus, Gallo describes their remarkable ability to camouflage themselves by changing not only their color but also their skin texture to match their surroundings. This adaptation helps the octopus avoid predators and ambush prey effectively.
3. Both Gallo and Widder's talks address the topic of bioluminescence among sea creatures. They mention similar uses of bioluminescence, such as communication, attracting prey, and deterring predators.
However, while Gallo focuses on various underwater creatures and their adaptations, including bioluminescence, Widder's talk is more specifically centered around bioluminescence and its role in the deep sea. The main difference between the two talks is the emphasis on different aspects of underwater life and adaptations.

The Mendelian gene is the basic unit of heredity, whereas the molecular gene is a DNA sequence of nucleotides that is converted into functional RNA.
As part of gene expression, the DNA is initially converted into RNA. The RNA could directly carry out a function or act as a template for a protein to carry it out. Genes are passed from an organism's ancestor to its offspring, allowing phenotypic features to be inherited. These genes combine to form various, distinctive genotypes, or DNA sequences.

How does sexual reproduction contribute to genetic variation
Genetic diversity is developed during sexual reproduction because the sperm and eggs that are produced have different gene combinations than their parent organisms.
Offspring through sexual reproduction could have a very diverse genetic makeup. This variation results from gametes randomly joining together after fertilisation, independent assortment, and crossing-over during meiosis.
As alleles in gametes are randomly divided and reassembled after fertilisation, genetic variety results. During meiosis, when homologous chromosomes are crossed over or their gene portions are swapped, genetic recombination also takes place.
Animals with albinism, cheetahs with stripes, flying snakes, play-dead animals, and mimicking plants are a few examples of genetic variety in animals.
