Question 1

Angiosperms can be dioecious or monoecious and they go through sexual production (Raghavan, 1999). Angiosperm flowers are considered to be hermaphroditic or androgynous because the same flower contains both female and male gametophytes. However, angiosperm flowers with only female gametophytes are incomplete and considered to be either a carpellate flower containing only female parts or a staminate flower containing only male structures. The male reproductive structure of the angiosperms is known as andoecium. The anthers that are found in the stamens of the angiosperms contain pollen sacks, which have the microsporocytes. The cells go through a process known as ...

Hemp is a traditional plant that has been used in the production of various products. Such products include cosmetics, insulation, and construction materials.

Commercial cultivation of hemp is prohibited in certain countries. The anatomy and structure of the plant suit its industrial functions. This paper examines the anatomy, structure, development, as well as the growth patterns of the plant. Additionally, it explores uses, ecological niche, and the differences between a male as well as ...

What are the female reproductive parts of the angiosperm flower?

The female reproductive parts of a flower include the stigma, the ovary, and the style. Their collective name is normally referred to as carpel. a flower may be composed of one or several pistils. For reproduction to occur, all these parts play an important role. The stigma is the female part of a flower that receives pollen grains. It normally has a sticky surface to enable pollen grain to stick and germinate on it. There are several shapes of the stigma. The different shapes enable them to be well adapted to their role in reproduction. Some of the shapes ...

Over a period of 400 million years, animals in the vertebrate category have evolved to a diverse array of life adaptations on earth. Vertebrates represent animals that are most familiar with people and are used for food, adopted as pets and deployed for labor. They include fish, reptiles, birds, amphibians and mammals. The classification system that groups vertebrates according to each of the classes that have been mentioned above utilizes genetics, anatomy, and the evolutionary relationships. Animals are classified starting with the kingdom which is a large body that encompasses animals that have similar characteristics and end up with ...

The research involved going through already existing information provided in accredited books, journals and websites. The research first explores the information that surrounds the positive side of surrogacy before delving into the negative side of the issue. Further reviews ...

Trisomy

Chromosomes are marvelous things! They carry in their genes the entire genetic code required to build a human being. Comprised of nucleic acid (DNA) and proteins, twenty-three pairs of chromosomes located in the cell nucleus are needed for the normal development of a human embryo. However, sometimes things go wrong. This paper will discuss some of the consequences of faulty chromosome separation during fertilization, resulting in Trisomy. Trisomy is a chromosomal condition which occurs when three chromosomes, instead of the normal two are produced during cell division. This happens due to the failure of human chromosome pairs to separate ...

Q1. Explain the regulation of the cell cycle

Every cell is regulated by particular checkpoints to ensure that the daughter cells are exact duplications. This is to help guarantee that cell mutations are not passed on to the next generation of cells. In eukaryotic cells, there are three main checkpoints. These are points at which cell replication can be halted until certain conditions are met (Boundless, 2016). The first checkpoint is near the end of the G1 phase. It is here that DNA gets evaluated and checked for damage. If damage has occurred, it either gets corrected or gets prevented from moving on to the next phase ( ...

Introduction

With the escalation in cost production and environmental concerns, researchers have in the recent past focused in investigating resourceful means of increasing yields while reducing fertilizer use. Arnall & Godsey assert that the seeding rate and hybrids that promise the highest crop populations is continuously sort by corn cost cultivators worldwide (2013). Nielsen et al. notes that the crop populations are tied to the end yields. Corn populations have greatly increased in Indiana over the past thirty years to make about 340 plants ...

Cloning is the process that a cell or an organism is produced asexually; meaning that no sex is involved in their formation and the product is identical to a specific ancestor. Animal cells are cloned simply because they can be produced from one fertilized cell and they are also genetically identical. In simpler terms, cloning is the process of producing many duplicate cells of an organism. In some cases, cloning is a natural process shown bacteria which are single celled, as well as identical twins in human beings and mammals. The process is also made possible to the animals ...

Reproduction in the News

Introduction Science and technology are marching forward into the brave new world with increasing rapidity. The proverbial Moore’s Law, prophesying the doubling of the speed of computer chips every six months (Moore’s Law), remains true to this date. As a corollary, increased use of the computing power and consequent technology allows medical science to unravel mysteries hitherto opaque to man. The biggest mystery to man has always been the mystery of procreation. As with most things man did not understand to begin with, he gave procreation a divine status. Children were literally the gift of God. However, ...

Utilitarianism is a form of normative ethics. According to Utilitarianism, an action will be classified as moral or immoral based on the end result that comes from such an action. Therefore, Utilitarianism classifies a moral action as any action that maximizes utility (Graham 121-161). Utility refers the wellbeing of the sentient entities in the society which arises from the aggregate good that arises from the action. In order to understand the good, the concept of hedonism is applied. According to hedonism, anything is deemed to be good if it led to pleasure (Graham 39-52). Nonetheless, the concept of hedonism ...

When an oocyte and spermatozoa fuse, the process is referred to as fertilization. The gametes are haploid at that stage and grow further into a diploid zygote. There is a difference in the forms that the process can be made possible. It can be through the natural mode that occurs in vitro or can happen outside the body in vivo (Hill, 2016). Research studies have been done adequately to ensure that circumstances that support life out of the womb can be created for a while before a transfer is done to the womb for future growth and development. For ...

Birth control is a practice that helps us to plan the timing of pregnancy as well as prevent pregnancy. Just like Vaginal ring and birth control patches, birth control pills regulate the oestrogen and progestin hormone levels in the body. The pills are taken as progestin-only or combination pills which have both the oestrogen and progestin. They work by preventing ovulation thereby inhibiting fertilization. Besides, they make the cervical mucus thicker which reduces chances of sperm to reach the egg. The oestrogen and progestin-based methods are very effective when administered at the right time as prescribed. They are also ...

The recent developments in technological advancements and scientific breakthroughs have presented modern ways of creating new things and doing things.

Introduction

Genome imprinting is the latest technique that has genetically modified the face of infertility; it is an epigenetic phenomenon through which the parental origin of a gene is determined based on its expression. 1 There are a vast number of genes in mammals that are marked with their parental origin, and the result of this phenomenon is a single parental allele. These marked genes are known as “imprinted.” They rely on the epigenetic machinery determining their parental identity and maintaining their origin-specific gene expression. There are 100 imprinted genes estimated in human and 200 ...

INJECTABLE CONTRACEPTIVES

Contraceptives can be dated from way back in the biblical era and there have been significant efforts to make improvements over the years to the various birth control methods. In the more recent days there are more than a dozen birth control methods practiced in the society. Some of this birth control methods include hormonal, oral, surgical and more commonly the physical methods of contraceptive. For one to be significantly protected from sexually transmitted illness and the unplanned pregnancies the more important thing is awareness and education on various methods available to them.

Injectable contraceptive

Contraception could be defined as the ...

Is this an appropriate reason to become pregnant?

Advance in technology can often raise issues regarding their application in everyday life. There are various moral considerations that arise in association with the ability to choose specific features of children when they are born. The advent of in vitro fertilization (IVF) has given parents the opportunity to decide specific characteristics of their children at an early stage. The underlying issue of the case is whether or not they should have a child that is matched with their sick child's tissue type so that they can obtain a transplant. While this would be of great medical benefit it presents ...

Original DNA Strand:

3’-TACCCTTTAGTAGCCACT-5’

Transcription (base sequence of RNA):

5’-UTGGGUUUTCUTCGGTGU-3’

Translation (amino acid sequence):

3’-TACCCTTTAGTAGCCACT-5’

What is the significance of the first and last codons?

Explanation: The first and last codons are very essential in that they dictate and command the direction of the transcription and synthesis of mRNA from the 5’ end towards the 3’ ends. Additionally, the first and last codons act like terminal points where protein synthesis begins and where it actually ends hence these codons actually determine the size of the animo acids produced which determine the type of and size of protein synthesized (Hartl, 2011).

What meaning do these codons have for protein synthesis?

Explanation: These codons are ...
