It is false that Oocytes do not complete meiosis II before they are fertilized. Meiosis II in oocytes is only completed if the oocyte is fertilized by a sperm.
What is oocytes?Oocytes are the immature female reproductive cells that have the potential to develop into mature eggs (or ova) when they are stimulated by hormones during the menstrual cycle. Oocytes are produced in the ovaries of female animals, including humans, and are stored in small sacs called follicles until they are released during ovulation. In humans, oocytes begin to develop before a female is even born, and at puberty, the menstrual cycle begins, and oocytes start to mature and become capable of being fertilized by sperm. Each oocyte contains half of the genetic material required to create a new human, and when a sperm fertilizes an egg, the two haploid cells combine to form a diploid zygote that will develop into an embryo.
Here,
When an oocyte is released from the ovary during ovulation, it is arrested in metaphase of meiosis II. If the oocyte is not fertilized, it will not complete meiosis II and will eventually degenerate.
However, if the oocyte is fertilized by a sperm, it will complete meiosis II and form a mature haploid egg (or ovum) that can fuse with the sperm to form a diploid zygote.

In an electron transport chain, energy is captured from electrons as they are passed between proteins called electron carriers.
What is electron transport chain?An electron transport chain is a series of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors via redox reactions and couples this electron transfer with the transfer of protons across a membrane.
Electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.
The associated electron transport chain is NADH → Complex I → Q → Complex III → cytochrome c → Complex IV → O2 where Complexes I, III and IV are proton pumps, while Q and cytochrome c are mobile electron carriers.

what do primates generally have at the end of their digits?The hands and feet of all primates have five digits. Most have flat nails and sensitive areas on the ends of their digits.
That is correct. Most primates, including humans, have flat nails or broad and flattened fingertips at the end of their digits, which are used for grasping and manipulating objects with precision.
Compared to other mammals, primates have highly sensitive areas at the tips of their digits, which contain many nerve endings and tactile receptors that provide them with a sense of touch and allow them to feel fine textures and shapes. This sensitivity is important for tasks such as grooming, feeding, and using tools.
However, some primates have evolved different adaptations depending on their ecological niche. For example, some primates such as marmosets and tamarins have sharp claws on their fingers and toes, which they use for climbing and grasping tree trunks and branches.
Other primates like gorillas have flat nails but also possess a pad of tough, fibrous tissue on the fingertips called a "dermal ridges" that helps them grip tree bark and other surfaces.

Are inner mass cells derived from the blastocyst?
The blastocyst is a hollow sphere that is composed of two distinct populations of cells: the outer trophoblast cells, which will give rise to the placenta, and the inner cell mass (ICM) cells, which will give rise to the embryo proper.
The ICM is a cluster of cells located at one end of the blastocyst, and it is the source of all embryonic stem cells. These cells are pluripotent, meaning they have the ability to differentiate into any cell type in the body. The ICM is the precursor to the three primary germ layers (ectoderm, mesoderm, and endoderm), which give rise to all of the organs and tissues in the body.
The process of ICM formation is a complex one and involves several key molecular and cellular events. After fertilization, the zygote undergoes a series of cell divisions to form a compact ball of cells called the morula. This structure then undergoes a process called compaction, in which the cells on the inside of the ball become more tightly packed than those on the outside. This creates an inner and outer population of cells, and the inner cells go on to form the ICM.

The process of phages carrying prokaryotic genes from one host cell to another is known as transduction.
Transduction is a type of horizontal gene transfer where genetic material is transferred from one bacterial cell to another through the action of bacteriophages (phages).
During transduction, a phage infects a donor bacterial cell and replicates inside it. As the phage replicates, it can accidentally package a piece of the donor bacterial DNA into its viral capsid instead of its own DNA.
This can happen when the phage mistakenly cuts the donor's bacterial DNA instead of its own DNA. When the phage leaves the donor cell and infects another bacterial cell, it injects the packaged DNA into the recipient cell, effectively transferring the donor bacterial DNA into the recipient cell.
