cotyledons
coleoptiles
meristems
hypocotyl and radicle
In eudicot seeds, the cotyledons are the seedling leaves and have absorbed much of the endosperm.
What is cotyledon?A seed's embryo contains a leaf-like structure known as a cotyledon. Cotyledons contribute to the provision of the nourishment a plant embryo requires in order to germinate and become established as a photosynthetic organism. Cotyledons may themselves be a source of nutritional reserves or may assist the embryo in metabolizing nourishment stored in other parts of the seed.
When it comes to certain seeds, the cotyledons are the organs responsible for the absorption of nutrients from the seed's stores. These cotyledons will subsequently expand when exposed to light and become the seed's first photosynthesis-producing organs.
In many monocots, the cotyledon serves as a specialized organ of absorption that is responsible for the mobilization of reserve materials and the withdrawal of these elements from the endosperm. Regardless of whether cotyledons aid in the absorption of nutrients from the endosperm or store the nutrients themselves, these embryonic seed leaves often do not survive for an extended period of time following germination.

T/F micelles, made of bile salts, have hydrophilic and hydrophobic regions that allow them to emulsify fats and dissolve in water.
The given statement is true. Micelles, which are spherical structures made of bile salts, have both hydrophilic and hydrophobic regions.
In the digestive system, bile salts are secreted by the liver into the small intestine, where they help to emulsify fats in the chyme (the mixture of partially digested food and digestive juices). The hydrophobic ends of the bile salts surround the droplets of fat, while the hydrophilic ends face outwards and dissolve in the watery environment of the intestine. This creates tiny droplets of fat, known as micelles, that are more readily soluble in water.
The micelles can then be taken up by the enterocytes, the absorptive cells that line the small intestine, where they are further broken down by lipases and other digestive enzymes into fatty acids and monoacylglycerols. These molecules can then be absorbed into the bloodstream and transported to cells throughout the body for use as a source of energy or for other metabolic processes.
Overall, the ability of micelles to emulsify fats and dissolve in water is critical for the efficient digestion and absorption of fats in the small intestine.

what are the characteristics of smooth muscle tissue?
Answer:
see below
Explanation:
Smooth muscle tissue is characterized by its ability to contract, but only when stimulated by nerve fibers. The contraction of smooth muscle tissue is usually not sustained, but it can be maintained for long periods of time.
The composition of smooth muscle tissue is also different from that of skeletal and cardiac muscle. Smooth muscle cells lack the striations seen in other types of muscle, and they do not contain myofibrils like skeletal or cardiac muscles do. Instead, smooth muscle cells are composed primarily of actin and myosin filaments arranged in a pattern that allows them to contract.

The chromosome number in the primary oocyte has reduced by half after meiosis I. At the end of meiosis I, the sister chromatids separate and are no longer connected at the centromeres as the centromeres do divide in anaphase I of meiosis.
What is meiosis?Meiosis is a type of cell division that results in the formation of gametes, such as sperm and eggs, with half the number of chromosomes as the parent cell. This reduction in chromosome number is necessary for the proper formation of offspring during fertilization, as the resulting zygote will have the normal diploid chromosome number for the species.
Meiosis occurs in two distinct stages, called Meiosis I and Meiosis II, that each involve two rounds of chromosome division. During Meiosis I, homologous chromosomes pair up and exchange genetic material, a process called crossing over. Then, in anaphase I, the sister chromatids separate and are distributed to opposite poles of the cell. In Meiosis II, the chromosomes separate, and the cells divide, producing four haploid daughter cells.

A pedigree diagram expresses the relationships of individuals, their gender, and the presence / absence of a specific trait. To be of much use in a genetic analysis, the pedigree must include several generations, preferably from a family with many children.
Objectives:
To familiarize students with the construction of human pedigrees. Students will apply their knowledge of inheritance patterns to pedigrees. Students will identify the relationships between individuals in a pedigree and determine what inheritance pattern is present in a family based on which individuals in the pedigree are affected and unaffected. Then students will assign individuals who are represented in a pedigree genotypes based on clues they interpret from the pedigree.
Pedigrees 1 - 5 can be found in the WORD or PDF files below this assignment in the weekly Moodle block
Consider the pedigree for cystic fibrosis. (See Pedigree 1.) An autosomal recessive gene (f) causes serious respiratory difficulties that usually lead to death of afflicted people by their late 30’s.
The generations are indicated by the Roman numerals on the left side of the pedigree. The members of each generation (related or not) are indicated by Arabic numbers. Females are represented by circles and males are represented with squares. Individuals with cystic fibrosis are shaded gray (or black). Thus, the 2 affected individuals are those in the 3rd generation: III-2 and III-4.
You have already learned about the inheritance pattern of CF. However, you could have inferred it from the pedigree. Because the disease only affects siblings in one generation, the disease is most likely to have autosomal recessive inheritance.
Because we know that cystic fibrosis is autosomal recessive, we can write the genotypes (entirely or in part) of all of the individuals in this family tree. Recessive homozygous individuals (ff) express the disease. Each normal individual has at least 1 dominant allele (F). We know that the individuals II – 2 and II – 3 are heterozygous (because this couple has a child with CF). The genotypes of the other 2 individuals in generation II can only be written as F_ because we do not know if they are FF or Ff.
QUESTIONS:
1. Using pedigree 1, list all of the possible genotypes of these individuals:
HINT: the easiest way to do this is to write letters (alleles) in, on the pedigree, for the people you know for sure. In this case, write the genotype that is homozygous recessive under the affected people. Then write out the genotypes of other individuals that you can infer. After you have filled in the genotypes on the pedigree, then fill out this chart.

II-1
II-2
II-3
III-1
III-2

2. Look at PEDIGREE #2. Do you think the trait shown is autosomal dominant or autosomal recessive? List all of the characteristics of the pedigree that justify your answer.
Use the letters "B" and "b" for the alleles.
3. What is the most likely genotype of individual I-2?
4. What does the notation like an upside-down T between II-3 and II-4 mean?
5. What is the chance that III-3 will have an affected child?
6. What is the chance that III-4 will have an affected child?
7. What is the genotype of individual III-2?
The family depicted in PEDGIREE #3 has some individuals with achondroplasia, a form of dwarfism. Note: (1) The homozygous dominant genotype is lethal; unfortunately infants with this genotype have such small ribs they cannot breathe at birth. (2) All of the people in the pedigree who have the dominant allele have the express the achondroplasia phenotype.
8. For each of the Genotypes listed below write every individual in pedigree 3 that has that genotype (Write then as “I-1, I-2, etc):
Individuals with genotype "AA"
Individuals with genotype "Aa"
Individuals with genotype "aa"

What would happened to a species, if they reproduced sexually but only underwent mitosis and not meiosis?
Answer:
If a species only underwent mitosis and not meiosis, they would not experience genetic recombination and diversity, leading to a lack of adaptation to changing environmental conditions. Over time, the species would become increasingly vulnerable to diseases and environmental pressures, potentially leading to its extinction. Additionally, without meiosis and its associated reduction of chromosome number, the number of chromosomes would increase with each generation, potentially causing problems with cellular function and viability.

A population of 40 guinea pigs undergoing natural selection is reduced to 20 individuals in only five generations. At this point genotype frequencies are 0.25, 0.5, and 0.25 for the genotypes AA, Aa, and ag, respectively. Assume that natural selection continues to act on this population. Is the population in Hardy-Weinberg equilibrium? Why or why not?
No, the population is not in Hardy-Weinburg equilibrium because the populations described here are being subjected to natural selection and does not have a large size.
The Hardy-Weinberg principle presupposes that a population is sizable and not undergoing natural selection, sexual selection, migration, or mutation, and have a large population. Even though no population in the real world can meet all of these requirements, the concept nonetheless provides a valuable framework for population analysis. As the population of pigs in the query is reduced and is undergoing natural selection, the population is not in equilibrium.
According to the Hardy-Weinberg principle, a population's genotype and allele frequencies will not change in the absence of any evolutionary processes. p + q = 1, where p is the frequency of the dominant allele and q is the frequency of the recessive allele, can be used to calculate the frequency of alleles in a population.
