The brain, being a vital organ, is protected by several anatomical features that help safeguard it from external injury. Two such features are:

1- Skull (Cranium): The brain is enclosed within the rigid structure of the skull, known as the cranium. The cranium provides a sturdy and protective covering around the brain, shielding it from direct physical trauma.

2- Meninges: The brain is further protected by three layers of protective membranes called meninges. These membranes, consisting of the dura mater, arachnoid mater, and pia mater, surround and cushion the brain. The meninges provide a barrier between the brain and the skull, acting as a shock absorber and reducing the impact of external forces.

Together, the skull and meninges provide crucial protection to the brain, reducing the likelihood of external injury and maintaining its structural integrity.

The longest time horizons are likely to be set by pension funds. Pension funds typically have long-term investment objectives as they are responsible for providing retirement benefits to individuals over an extended period of time.

These funds aim to accumulate and grow assets over many years to meet future pension obligations. Therefore, pension funds are often inclined to invest in assets with longer maturity profiles, such as equities, real estate, and long-term bonds, which align with their long-term investment horizon.

While banks and property and casualty insurance companies also manage investments, their time horizons are generally shorter compared to pension funds. Banks focus on liquidity and shorter-term lending activities, while property and casualty insurance companies primarily manage risks associated with property and liability claims. While they may have some longer-term investments, their overall time horizons are typically shorter than those of pension funds.

Polyp and medusa jellyfish can produce female offspring through parthenogenesis.  

Parthenogenesis is a form of reproduction in which offspring are produced without the involvement of a male. In some species, including some jellyfish, females can produce offspring through parthenogenesis if they are not able to mate with a male or if the male is not present.

This process involves the activation of an egg cell, which then divides and forms a clone of the mother. The resulting offspring are genetically identical to the mother, and are usually female, as males are produced through a different process involving fertilization. This means that parthenogenesis can be used to produce all-female populations of jellyfish.

The correct option is A, Meiosis produces gametes that contain one complete haploid set of chromosomes'.

Meiosis is a specialized type of cell division that occurs in sexually reproducing organisms. It consists of two successive divisions, resulting in the production of four daughter cells, each with half the number of chromosomes as the parent cell. Meiosis plays a crucial role in the generation of gametes, such as sperm and eggs, which are essential for sexual reproduction.

During meiosis, the DNA in the parent cell is replicated, and then two rounds of division occur. The first division, called meiosis I, separates homologous chromosomes, while the second division, meiosis II, separates sister chromatids. This process ensures that the daughter cells produced have the correct number of chromosomes and genetic diversity.

Cancer hallmarks self-sufficiency is associated with oncogene, insensitivity to antigrowth signals is associated with oncogene, evasion of apoptosis is associated with both, limitless replicative potential is associated with neither, sustained angiogenesis is associated with both, tissue invasion and metastasis is associated with both.

Self-sufficiency in growth signals:

Associated with: Oncogene (O)

Explanation: Self-sufficiency in growth signals means that cancer cells can grow and divide without requiring external signals. This is typically driven by mutations in oncogenes, which are genes that promote cell growth and proliferation. An example is the HER2 (human epidermal growth factor receptor 2) oncogene, which is involved in breast cancer. Overexpression of HER2 leads to uncontrolled cell growth and division.

Insensitivity to antigrowth signals:

Associated with: Oncogene (O)

Explanation: Insensitivity to antigrowth signals refers to the ability of cancer cells to ignore signals that would normally inhibit cell division. Mutations in oncogenes can disrupt these inhibitory signals, allowing uncontrolled growth. An example is the RAS oncogene, which is frequently mutated in various cancers. Mutant RAS proteins lead to continuous signaling for cell growth, bypassing normal regulatory mechanisms.

Evasion of apoptosis:

Associated with: Both (B)

Explanation: Evasion of apoptosis refers to cancer cells' ability to avoid programmed cell death, which is a natural mechanism for removing damaged or abnormal cells. Both oncogenes and tumor suppressor mutations can contribute to this hallmark. For example, the BCL-2 oncogene inhibits apoptosis by preventing the release of pro-apoptotic proteins. On the other hand, mutations in tumor suppressor genes like p53 can disrupt apoptosis pathways, leading to cell survival even when it should undergo programmed cell death.

Limitless replicative potential:

Associated with: Neither (N)

Explanation: Limitless replicative potential refers to cancer cells' ability to divide indefinitely, bypassing the normal limits of cellular replication. This hallmark is not directly associated with oncogenes or tumor suppressor mutations but is instead related to the maintenance of telomeres, which are protective structures at the ends of chromosomes. Telomerase, an enzyme that maintains telomeres, is upregulated in cancer cells, allowing them to continually replicate without reaching the Hayflick limit.

Sustained angiogenesis:

Associated with: Both (B)

Explanation: Sustained angiogenesis refers to the ability of cancer cells to stimulate the growth of new blood vessels to supply nutrients and oxygen. Both oncogenes and tumor suppressor mutations can play a role in this process. For example, the VEGF (vascular endothelial growth factor) pathway is often upregulated in cancer, promoting angiogenesis. Mutations in tumor suppressor genes like p53 can also affect the balance of pro- and anti-angiogenic factors, contributing to sustained angiogenesis.

Tissue invasion and metastasis:

Associated with: Both (B)

Explanation: Tissue invasion and metastasis refer to cancer cells' ability to invade surrounding tissues and spread to distant sites in the body. Oncogenes can drive the invasive and metastatic properties of cancer cells by promoting processes like epithelial-mesenchymal transition (EMT), which allows cells to detach from the primary tumor and invade surrounding tissues. Tumor suppressor mutations, such as in the TP53 gene, can also contribute to tissue invasion and metastasis by affecting cell adhesion and migration pathways.

The notion of a happy and simple family structure implies a sense of stability and contentment within the family unit. It suggests that adhering to these traditional roles and norms would lead to a harmonious family life.

However, it's important to recognize that the Father Knows Best model represents a particular idealized image of family life in the 1950s.

Galactic rotation curves refer to the plot of the rotational velocity of stars or gas clouds within a galaxy as a function of their distance from the galactic center. According to the laws of Newtonian gravity, the rotational velocity of objects within a galaxy should decrease as the distance from the galactic center increases. This is because the gravitational force exerted by the visible matter (stars, gas, etc.) in the galaxy diminishes with distance.However, observations of galactic rotation curves have revealed a different pattern. Instead of the expected decrease in rotational velocity with increasing distance, the observed rotational velocities tend to remain relatively constant or even increase in the outskirts of galaxies.
