Explain how seed germination is caused by a combination of genetic and environmental factors? please help me im failing science!!
Answer:Germination is the process of seeds developing into new plants. First, environmental conditions must trigger the seed to grow. Usually, this is determined by how deep the seed is planted, water availability, and temperature. When water is plentiful, the seed fills with water in a process called imbibition. The water activates special proteins, called enzymes, that begin the process of seed growth. First the seed grows a root to access water underground. Next, the shoots, or growth above ground, begin to appear. The seed sends a shoot towards the surface, where it will grow leaves to harvest energy from the sun. The leaves continue to grow towards the light source in a process called photomorphogenesis.

Sexual reproduction in animals depends on the production of gametes. Which of these processes produces gametes in animals?
Answer options:
Mitosis Fertilization Meiosis Binary FissionAnswer:
Meiosis
Explanation:
Meiosis is a specialized type of cell division that produces gametes. Diploid parent cells, after DNA replication, undergo two rounds of meiosis to produce four haploid gametes.
Mitosis produces daughter cells for growth and repair of organisms. It produces two identical daughter cells from a parent cells.
Fertilization is when two gametes fuse to create a zygote.
Binary fission is when bacteria undergo asexual reproduction to produce two identical daughter cells.
Option C is correct. the gametes in animals are produced by Meiosis.
Meiosis:
It is a type of cell division in which a cell divide to form four Haploid daughter cells.
It usually occurs in the germ cells to produce gametes.Meiosis is completed in 2 phases.Gametes fertilise to form zygotes.In binary fission is cells divide to form 2 nearly identical cells. In Mitosis, cells divide to form two identical diploid cells.Hence, Options A, B, and D are incorrect.

What is a disadvantage for organisms that reproduce asexually rather than sexually?
Answer:
A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilized by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species, however, outweighs this disadvantage.

What is base pairing?A base pair is a fundamental unit of double-stranded nucleic acids that consists of two nucleobases that are hydrogen-bonded to each other.
They are the building blocks of the DNA double helix and contribute to both DNA and RNA's folded structure.
A and T and C and G are two pairs of bases that pair off in a double helix structure. RNA lacks thymine bases in favor of uracil bases (U), which pair with adenine.
Watson-Crick (canonical) nucleobase pairs are required for double-stranded DNA (dsDNA) integrity and genetic information fidelity.

Realiza los dibujos correspondientes en tu libreta. 2.- Realiza una conclusión de lo aprendido en tu clase, por incisos, números o puntos
Answer:
1.Ratón: se ubica en el segundo nivel trófico, es un consumidor primario que se alimenta de semillas
semillas (productores)---->ratón (consumidor primario)-->serpiente(consumidor secundario) --->zorro(consumidor terciario)
2.
Hay 4 niveles tróficos.En el primer nivel se encuentran los productores.En el segundo nivel se encuentran los consumidores primarios, estos se alimentan de los productores.En el tercer nivel se encuentran los consumidores secundarios, los cuales se alimentan de los consumidores primariosEn el cuarto nivel se encuentran los consumidores terciarios que se alimentan de los consumidores secundarios.Al consumir lo que se encuentra en el nivel anterior obtienen energía para subsistir y mantener el equilibrio del ecosistema.Los niveles tróficos son los lugares que ocupan un determinado grupo de seres vivos en relación a otros por la energía que tienen y que pasan al siguiente nivel. Se ve en la cadena alimentaria, donde la energía que se obtiene de los nutrientes del nivel anterior siempre es destinada a seres mas grandes en tamaño, es decir que están en el siguiente nivel trófico y necesitan mas energía.Explanation:
El ratón es un animal herbívoro, es decir que se alimenta de plantas y hierbas, por ende se ubica en el segundo nivel trófico porque consume a los productores. Estos últimos reciben este nombre porque producen su propio alimento a diferencia del resto de los niveles en donde los seres vivos se alimentan de animales o insectos que estén en niveles inferiores.
La energía que obtiene el ratón al consumir a los productores se utiliza en el metabolismo y en las diferentes reacciones que hacen que se mantenga vivo hasta que este es consumido por otro animal transfiriendo la energía al siguiente nivel. Esta cadena sigue hasta llegar al consumidor terciario. En todos los niveles intervienen los descomponedores que degradan los restos de los seres vivos para obtener energía y nutrir la tierra, de esta forma comienzan nuevamente la cadena alimentaria.
which of the following changes would most likely lead to a mammal population exceeding its carrying capacity
Answer:
Growth rate becomes negative.
Explanation:
Growth rate becomes negative when a mammal population exceeding its carrying capacity because the environment can't sustain the extra population due to limited resources of that environment. Every environment has a limited resources such as food, water and shelter etc, and due to these limited resources limited number of organism can live in that environment so when the population exceeds, the growth becomes negative.
A decrease in the food supply immediately after offspring are born would most likely lead to a mammal population exceeding its carrying capacity.
The question is incomplete, the complete question is;
Which of the following changes would most likely lead to a mammal population exceeding its carrying capacity?
An increase in mortality of adults during mating season
A decrease in the food supply immediately after offspring are born
An increase in the number of predators immediately after offspring are born A decrease in the number of adult females during mating season
Mammals are organisms that give birth to their young ones alive. The carrying capacity of a population refers to the number of individual organisms that can be supported by a particular habitat at a given time. The carrying capacity of a habitat depends on; availability of food, shelter, water, and mates.
When there is a decrease in the food supply immediately after offspring are born, the habitat can no longer support the new individuals owing to scarcity of food hence the mammal population has exceeded its carrying capacity.

and eggs) and seeds (fertilized eggs) *
shoot system
reproductive system
Phloem
xylem
The part of the plant that is involved in the production of gametes is known as the carpel. It contains the ovary where the eggs, or ovules, are located.
How gamete is produced in angiosperm?In angiosperms, gametes are produced by the gametophyte generation. Angiosperm gametophytes are associated with flowers. The gametes they produce join to form the sporophyte.
Within the flower, sperm cells are produced by pollen at the tips of stamens, while egg cells develop in ovules, tiny structures embedded in the ovary at the base of the pistil.
Stamen and carpel are the male and female reproductive structures of the plant, respectively. Both pollen and egg are fertilized in order to produce seeds which refer to the reproductive system of the plant. While the phloem and xylem govern the shoot system of the plant.
Therefore, the part of the plant that is involved in the production of gametes is known as the carpel. It contains the ovary where the eggs, or ovules, are located.

Explanation:
The type of mutation is responsible for the change in the mRNA base is missense mutation. The correct option is B.
What is missense mutation?A genetic change in which a single base pair replacement changes the genetic code in such a way that such an amino acid other than the customary amino acid at that location is produced.
The main distinction among both nonsense as well as missense mutation is that the former introduces a stop codon into the gene sequence, resulting in premature chain termination.
While the second tries to introduce a distinct codon into the gene sequence, rather than a stop codon, resulting in a non-synonymous amino acid.
A missense mutation can be lethal or potentially cause Mendelian disease; it can also be mildly harmful, effectively neutral, or beneficial.
Thus, the correct option is B.

Why is it adaptive for plants to detect and respond to daily and seasonal changes?
Answer:
Like all organisms, plants detect and respond to stimuli in their environment. Their main response is to change how they grow. Plant responses are controlled by hormones. ... Plants also respond to daily and seasonal cycles and to disease.
Plants are known to detect and respond to the daily cycle of light and darkness. The reason why it is adaptive for plants to detect and respond to daily and seasonal changes is that plants are known to have Environmental stimuli that indicate changing seasons which therefore trigger other responses.
A lot of plants often respond to the days growing shorter in the fall where they go dormant. There are some varieties of plants that open their leaves during the day to collect sunlight and then close their leaves at night to prevent water loss.Some plant also hold their growth and development in order to survive the extreme cold and dryness of winter.
