Are most mutations bad?
Answer:
Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious. In general, the more base pairs that are affected by a mutation, the larger the effect of the mutation, and the larger the mutation's probability of being deleterious.
Explanation:
Answer:
It depends, not all mutations are bad.
Explanation:
Some mutations don't affect anything and remain coding for the same gene so it ends up being the same even if it wasn't mutated in the first place.

Answer:
d. the cells in primary cell cultures do not divide.
A key difference between primary cell cultures and secondary cell lines is that the cells in primary cell cultures do not divide.
hope it helped you
Explanation:
The main difference between primary and secondary cell culture is that the primary cell culture contains the cells directly obtained from host tissue, whereas the secondary cell culture contains sub-cultured cells from primary cell culture.

Explanation:
how does fertilization of angiosperm differ from fertilization in bryophytes
Answer:
Fertilization in flowering plants happens through a process called pollination. Pollination occurs when pollen grains from the anther land on a stigma. ... Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. After fertilization occurs, each ovule develops into a seed

Hypothesize and diagnose the impact of variability on enzyme ability
Which of the following are differences between DNA and RNA? Mark all that apply.
a- DNA nucleotides include: Adenine, Cytosine, Guanine and Thymine
b- RNA nucleotides include: Adenine, Cytosine, Guanine and Uracil
c- DNA normally exists as double stranded
d- RNA normally exists as single stranded
e- RNA normally exists as double stranded
f- DNA normally exists as single stranded
g- The sugar in DNA is a ribose
h- The sugar in RNA is a deoxyribose
Answer:
The correct answer is - a, b, c, d, g and h.
Explanation:
DNA and RNA both are nucleic acids and have considered genetic materials. There are certain difference in these molecules such as-
Different sugars present in the nucleotide, Deoxyribose sugar in DNA and ribose sugar in RNA.
There are different nitrogenous bases also present as RNA has uracil instead of thymine.
DNA normally found in double-stranded while RNA exists in single-stranded.

What would happen to the weight of an ice cub if it melted?
A) it would weigh a little more.
B) it would weigh a lot less.
C) it would weigh the same.
D) it would weigh a lot more.
Answer:
C. it would weigh the same
Explanation:
The mass of the ice doesn't change as the ice melts, so the volume displaced remains the same whether its is solid or liquid.
Discuss how the concept of "survival of the fittest" was developed and what it means.
Explanation:
Survival of the fittest is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection.In On the Origin of Species, he introduced the phrase in the fifth edition published in 1869, intending it to mean "better designed for an immediate, local environment".

¿Cuál es el rol de la genética microbiana en el contexto de la Biología?
¿Qué aplicaciones tiene la Genética Microbiana hoy en día?
¿En qué consiste el protagonismo de la Genética microbiana en el devenir histórico de la Biología?
Answer:
- La genética microbiana ha sido fundamental para la comprensión de diferentes mecanismo genéticos y evolutivos
- Los microrganismos son ampliamente utilizados en medicina y procesos biotecnológicos
- La microbiología ha permitido descartar la teoría de la generación espontanea (anteriormente aceptada en biologia) como así también formular nuevas teorías (hoy en día ampliamente aceptadas por la comunidad científica)
Explanation:
La genética microbiana juega un papel fundamental en biología, ya que los organismos microscópicos (por ejemplo, bacterias) poseen características únicas para el estudio de mecanismos genético/moleculares tales como, por ejemplo, 1-un corto tiempo generacional y 2-la capacidad de manipulación de un número de organismos muy alto (N muestral) en un laboratorio. En consecuencia, los microrganismos permiten estudiar mecanismos genéticos y evolutivos con mayor grado de precisión y versatilidad al ser comparados con organismos pluricelulares. La microbiología ha permitido el desarrollo de técnicas esenciales en el campo de la biología molecular: la técnica de edición genómica CRISPR-Cas9 se basa en el sistema adaptativo que poseen ciertas bacterias para hacer frente a infecciones virales. La biotecnología microbiana ha permitido también desarrollar diferentes tipos de alimentos y procesos biotecnológicos (por ejemplo, la cerveza y ciertos productos lácteos requiere la utilización de microrganismos para llevar a cabo el proceso de fermentación). Por otra parte, mediante técnicas de recombinación genética podemos explotar las características de los microrganismos para producir a gran escala ciertos productos biotecnológicos y medicinales (por ejemplo, producir insulina para uso humano). La microbiología emergió en la segunda mitad del siglo XIX y desde entonces ha posibilitado el desarrollo de importantes avances para el tratamiento y cura de enfermedades infecciosas, como así también descartar teorías tales como la generación espontánea y generar nuevos conocimientos en el campo de la biología y la genética (por ejemplo, el descubrimiento que el ADN se replica de manera semiconservativa fue realizado utilizando cepas de E. coli).

10. What processes found at hot spots will help form the following rocks? (4 points)
A. Metamorphic rocks
B. Igneous rocks
It’s not multiple choice I need a answer for both
Answer:
metamorphic rock
Explanation:
metamorphic rock simply means that the rocks have been geophysically altered. heat is always a primary source for alteratino of rock so the heat ofmolten rock generated by hot spots can easily cause an abundance of metamorphic rocks within the system
